The Linux Experiment

After playing with the GNOME Appearance preferences on my new Mint 8 installation, I managed to completely lose the color scheme, window decorators and other options for the default Helena theme – which I actually liked.

Due to an unrelated incident that I will blame on an abuse of Compiz (which really doesn’t play nice with the Xinerama extension), I recreated my GNOME profile this morning and saved out the default theme. For my own future reference (and anyone else who doesn’t want to nuke their profile), I’ve uploaded the default Mint 8 theme. Extract it to your ~/.themes/ directory and it will appear in Control Center > Appearance as “Default Mint Theme”.

This theme should theoretically work on any Linux distribution with GNOME, as well, but you’ll need the “Shiki-Wise” control set, “Shiki-Colors-Metacity” window border, and the “GNOME-Wise” icon set for more than just the gray and green hues.

While my initial plan for January was to stick with Windows 7 and perhaps try out Fedora 12, a bad DVD interrupted the Fedora install progress. Out of sheer convenience, I’d planned on running Linux Mint in a VM and had pulled the ISO earlier in the week. “Aha!” I thought. “I’ll install this instead of Fedora and see what’s what.”

My initial impressions are that Mint is perhaps the first Linux distribution that I’d enjoy using on a day-to-day basis. With only a few minor tweaks (activating multiple monitors and using optical out for sound), I have a completely functional desktop environment. Compiz is totally integrated into the experience, degrades gracefully if needed, and is used to enhance the UI rather than provide unneeded eye candy.

Taking a page out of Jon’s book, I also installed Banshee for media playback. What a difference from previous media player experiences – my BlackBerry was automatically detected, synced with my library and folders were built properly in the MediaCard/BlackBerry/music directory. Now, all I need is some better music and I’ll be set!

Last night I upgraded to Linux Mint 8 (Helena), x64 edition. Based on Ubuntu 9.10 (Karmic Koala), Helena has so far proven to be absolutely great and the panacea to my Linux problems. By far most of my issues with Gloria seemed to come from hardware incompatibility. Well, those are all in the past now.

Audio

There was a minor issue in Gloria with regards to my computer’s sound. Basically, although my laptop’s volume had something like 15 increments, Gloria shoehorned those into four categories: Really Goddamn Loud, Loud, Barely Audible, and Mute. That is no longer the case – I finally have the full spectrum of sound available on my laptop. At last, I can stream terrible YouTube videos and listen to them in the coffee lounge without being worried what the people ten tables down from me think!

Visual

First off, I have to compliment the appearance of Helena. The default theme is slick and very easy on the eyes, and the default background is excellent. I have approximately 50 wallpapers on my computer, and the fact that I haven’t changed it out of an ADD fit really speaks for the choice.

Now, onto more interesting matters: my media players work, my monitor works, and everything works damn well. In an earlier post, I documented Mint’s inability to take advantage of my brand new 1080p monitor. Unlike my previous experience, changing resolutions was a breeze and – most importantly – my monitor finally worked in full 1080p glory. At last, everything looks absolutely gorgeous. Watching videos has also been a much smoother experience in Helena. I’m not having any difficulty jumping to random spots in video files – previously, this would do anything between slowing down the video temporarily to crashing the media player. (As a note, I have no idea if Helena is actually responsible for “fixing” that last bit, but I’m willing to give them the benefit of the doubt here).

Other bugs

The desktop shift that I occasionally complain about is nowhere to be seen… yet. I never could figure out how to recreate it, so I can’t definitively say whether it has disappeared.

Compliments to the Mint people

Having seen what the open source community can do to improve and support a product, I have to say I’m extremely impressed with the work they’ve done. Just last week I stated that I would probably run a dual boot with Windows 7 as my primary system and Mint or Ubuntu as my secondary system. Well, after installing and using Helena, I have to say I’m strongly considering sticking with Mint and possibly having Windows 7 as a secondary OS for compatibility issues. I can definitely say that I wasn’t expecting a free operating system to work as well as this one does. Bravo.

The following is a cautionary tale about putting more trust in the software installed on your system than in your own knowledge.

Recently, while preparing for a big presentation that relied on me running a Java applet in Iceweasel, I discovered that I needed to install an additional package to make it work. This being nothing out of the ordinary, I opened up a terminal, and used apt-cache search to locate the package in question. Upon doing so, my system notified me that I had well over 50 ‘unnecessary’ packages installed. It recommended that I take care of the issue with the apt-get autoremove command.

Bad idea.

On restart, I found that my system was virtually destroyed. It seemed to start X11, but refused to give me either a terminal or a gdm login prompt. After booting into Debian’s rescue mode and messing about in the terminal for some time trying to fix a few circular dependencies and get my system back, I decided that it wasn’t worth my time, backed up my files with an Ubuntu live disk, and reinstalled from a netinst nightly build disk of the testing repositories. (Whew, that was a long sentence)

Unfortunately, just as soon as I rebooted from the install, I found that my system lacked a graphical display manager, and that I could only log in to my terminal, even though I had explicitly told the installer to add GNOME to my system. I headed over to #debian for some help, and found out that the testing repositories were broken, and that my system lacked gdm for some unknown reason. After following their instructions to work around the problem, I got my desktop back, and once more have a fully functioning system.

The moral of the story is a hard one for me to swallow. You see, I have come to the revelation that I don’t know what I’m doing. Over the course of the last 3 months, I have learned an awful lot about running and maintaining a Linux system, but I still lack the ability to fix even the simplest of problems without running for help. Sure, I can install and configure a Debian box like nobody’s business, having done it about 5 times since this experiment started; but I still lack the ability to diagnose a catastrophic failure and to recover from it without a good dose of help. I have also realized something that as a software developer, I know and should have been paying attention to when I used that fatal autoremove command – when something seems wrong, trust your instincts over your software, because they’re usually correct.

This entire experiment has been a huge learning experience for me. I installed an operating system that I had never used before, and eschewed the user-friendly Ubuntu for Debian, a distribution that adheres strictly to free software ideals and isn’t nearly as easy for beginners to use. That done, after a month of experience, I switched over from the stable version of Debian to the testing repositories, figuring that it would net me some newer software that occasionally worked better (especially in the case of Open Office and Gnome Network Manager), and some experience with running a somewhat less stable system. I certainly got what I wished for.

Overall, I don’t regret a thing, and I intend to keep the testing repositories installed on my laptop. I don’t usually use it for anything but note taking in class, so as long as I back it up regularly, I don’t mind if it breaks on occasion; I enjoy learning new things, and Debian keeps me on my toes. In addition, I think that I’ll install Kubuntu on my desktop machine when this whole thing is over.  I like Debian a lot, but I’ve heard good things about Ubuntu and its variants, and feel that I should give them a try now that I’ve had my taste of what a distribution that isn’t written with beginners in mind is like. I have been very impressed by Linux, and have no doubts that it will become a major part of my computing experience, if not replacing Windows entirely – but I recognize that I still have a long way to go before I’ve really accomplished my goals.

As an afterthought: If anybody is familiar with some good tutorials for somebody who has basic knowledge but needs to learn more about what’s going on below the surface of a Linux install, please recommend them to me.

GNOME Do is a fantastic little program that makes Linux Mint a very comfortable experience. At first glance, GNOME Do just looks like a collection of launchers that can be docked to your window, with a search function attached for completeness. What stands out about Do, though, is that the search function offers a lot of versatility. Through Do, I can launch programs, mount and unmount drives, bring up folders, and execute a variety of actions through the plug-ins. I’ve found that it saves me a lot of mouse movement (yes, I’m that lazy) when I’m working on assignments. In less than two seconds, I can call up Kate to start up my data entry, start up R in terminal, open the folder containing all of my data, and start a conversation in Pidgin. Best of all, since the search function can be called up with the Super+Space key combination, I can do all of this without ever having to switch windows.

I also find that Do helps to clean up the clutter on my desktop. I’ve got it set up as the Docky theme on the bottom of my screen. Since I have no need for the panel, I’ve got it set up to autohide at the top of my monitor. This means when I have something maximized, it legitimately takes up the entire monitor.

What a beautifully clean desktop.

Adding or removing programs to or from Do is a cinch too – it’s as simple as dragging and dropping.

Unfortunately, it’s not all great

Like every other Linux program, Do saves time and effort. Like every other Linux program, Do also costs time and effort in the bugs that it has. The most frustrating bug I’ve had so far is that Do simply disappears on a restart. It runs and in a manner it “exists” since I can resize it on my desktop, but I can’t actually see or use it. Apparently this is a known bug, and I haven’t been able to find a decent solution to it. It’s especially unfortunate because Do provides so much convenience that when it doesn’t work properly, I feel like I’m reverting to some primitive age where I’m dependent on my mouse (the horror!)

Notice how the cursor is cut off? In reality, it's a resizing cursor, used to resize an invisible panel. It technically does function, since after I reboot I find that GNOME Do inadvertently takes up half my screen.

Regardless, I’d recommend Do for anyone who can install it. When it works, it’s great for saving you some time and effort; when it doesn’t, well, ’tis better to have loved and lost….

Let me start off by saying that my experience thus far (over the last 24 hours) with Fedora 12 – Constantine has been the complete opposite from Tyler’s.  For the most part, at any rate.  While I, too attempted to do a preupgrade (from terminal) to Constantine and had it fail due to an insufficiently sized /boot partition – the 200 MB that it suggests on install is simply not enough – my clean install attempt went smooth as silk.

After backing everything important (user folder) up to my server, which over gigabit ethernet took all of 12 minutes, I popped the Fedora 12 x86_64 DVD into my drive and restarted.   Installation and drive partitioning was easy, as was customizing my installation repositories to include Fedora 12 x86_64 and Fedora 12 x86_64 updates – this has saved me a lot of headaches now, I’m sure.  I also decided this time around to add KDE at boot time, just to see if this would simplify my problems with that environment; more on that in a later post, I’m sure.

As of right now I’m running a stable – though desktop effects-less – Gnome environment.  Boot time over Fedora 11 has significantly improved, and the boot animation is a great improvement over the scrolling bar from Fedora 11.  In addition, off the bat my computer automatically supported native resolution (no-go without drivers in Fedora 11) and screen brightness changing (same story there in Leonidas).

One other thing that GREATLY excites me – folder mounting of my Windows Home Server shares has increased in speed tenfold.  It’s almost instant now, much like it would be in Windows – fantastic!

Though frustrated by the idea of having to re-configure Wine and vpnc (that took me FOREVER!), and waiting for nVidia or a kmod driver to come out that supports my GeForce 8600M GS for enabling desktop effects and my beloved Gnome DO, I’m pleasantly surprised by my experience thus far.

More to come soon!

Well, it’s official – twelve more days remain until the November 17 release of Fedora 12 (Constantine).  I, for one, can hardly wait – Fedora 11 has been rock-solid for me so far (under Gnome, anyways – but I’ll leave that subject alone) and I can only imagine that Fedora 12 is going to bring more of the same my way.

Among some of the more notable changes being made that caught my interest:

• Gnome 2.28 – the current version bundled into my Fedora 11 distribution, 2.26.3, has been nothing but amazing.  Unflinchingly stable, fast, and reliable – it’s everything I want in a desktop environment.
• Better webcam support – not sure how this can get any better from my perspective since my LG P300’s built-in webcam worked straight out of the box on Fedora 11, but I’m interested to see exactly what they bring to the table here
• Better IPv6 support – since our router does actively support this protocol, it’s nice to see Fedora taking charge and always improving the standard
• Better power management – for me, this is a major headache under Gnome (I know, I know…) since it really doesn’t let me customize anything as much as I would like to.   Among other things, it’s supposed to offer better support for wake-from-disk and wake-from-RAM.  We’ll see.

I’m sure that Tyler and I will keep you posted as the due date gets closer, and especially once we’ve done the upgrade itself!

This morning I reinstalled my Debian system. I began by downloading an ISO for the current Debian Stable build (called Lenny), and installing it with the graphical installer. That done, I used a couple of my old posts to get my wireless firmware installed and to upgrade my system to the Testing repositories.

Unfortunately, I have realized that a clean install of Debian Linux is a pretty plain place to be in. Even though I have the benefit of my old writings to help me get up to speed, some, like the ones dealing with how to get Compiz working properly, are somewhat lacking in detail.

Naturally, I’ve replaced all of the problems that running multiple desktop environments was causing with all of the problems that an entirely unconfigured system can cause. I’ve already mentioned that I haven’t gotten Compiz working yet (whenever I turn it on, all of my window decorations disappear), and there is some error with Postgre that causes Synaptic and Aptitude to complain whenever I make changes to my system:

E: postgresql-8.4: subprocess installed post-installation script returned error exit status 1
E: postgresql: dependency problems – leaving unconfigured
E: postgresql-contrib-8.4: dependency problems – leaving unconfigured
E: postgresql-contrib: dependency problems – leaving unconfigured

Most stressing is the fact that I cannot get into the preferences for the Nautilus file system browser. Whenever I try to open the preferences dialog from the edit menu, it (and most of GNOME) crash. Running Nautilus from the terminal yields me this output:

(nautilus:4213): Gtk-CRITICAL **: gtk_combo_box_append_text: assertion `GTK_IS_COMBO_BOX (combo_box)’ failed

(nautilus:4213): GLib-GObject-CRITICAL **: g_object_set_data_full: assertion `G_IS_OBJECT (object)’ failed

(nautilus:4213): GLib-GObject-CRITICAL **: g_object_get_data: assertion `G_IS_OBJECT (object)’ failed
Segmentation fault

Actually, the terminal prints output similar to the above, but so much of it that this post would take up most of the front page of the site were I to post it all. I have no idea what the hell any of that means, or how it got into my system, or why I cannot get into the preferences panel of Nautilus as a result.

Until I do figure it out, I’ll be spending a lot of time on the #debian channel. Along with these major problems come a number of small tasks, like adding myself to the sudo keyring, adding the Testing repository keys to my sources list so that it stops yelling that all of my software is unverifiable.

Fucking Linux.

If you’re like me, which you either are or are aspiring to be, then you hate having to manually resize dozens of images. Ubuntu, and Linux Mint, by extension, offers a great image resizing and rotation tool for Nautilus. This tool allows you to resize a batch of images very quickly and easily: you select the images, right-click, and select “Resize images”. You can select how you want to scale the images (the options presented are a preset ratio, a percentage of the original dimensions, or a custom size) and how you want them to be saved (you can append each copy with something like “RESIZED” or choose to simply replace the original image).

This tool is particularly handy if you’re looking to post some of your images online – having it around makes it much simpler and easier to resize several hundred images from, say, a vacation. Smaller images mean faster transfer times, and to some degree less concern about other people pilfering your high-resolution images (this is aimed more at a few social networking websites that like to claim ownership over their users’ photos).

This will be a brief reference post mostly for my own benefit, but a good fix for an issue where Compiz shows black boxes or invisible characters in the GNOME terminal when typing:

As for the text corruption issue… Is the “Force X and GLX synchronization” option enabled in the workarounds plugin in ccsm?

In my case, the option was enabled in CompizConfig Settings Manager, but the Workarounds plugin wasn’t:

Hopefully this is useful for those of you using the terminal on a regular basis! I’ll likely have a full update on switching back to GNOME and installing Compiz shortly.
