I’ve been doing a fair amount of experimentation on my machines. Been playing with XBMC, Boxee, Ubuntu, and bleeding-edge Xfce and Freedesktop software stacks on Gentoo.
First, I tinkered with the HTPC. It’s a Zotac MAG, dual-core Atom 330 with nVidia ION graphics. It’s just the thing for at 1080p media center. It was running an experimental community-built version of XBMC, installed back in January or February. While it was nice because it was extremely minimal, with just enough operating system to boot straight into XBMC, it was very buggy, and definitely alpha-quality.
So I wiped the disk and installed straight-up Ubuntu 10.04.1, and then installed XBMC and Boxee. I’m still tinkering with it; I need to setup the remote control I just bought, and I need to configure it to load a media center on boot, rather than the Gnome desktop. There have been a few hardware growing pains, mostly related to getting HDMI sound working correctly, and forcing 1080p output — detected my TV as a 720p device, so I had to fiddle with the nVidia utility to fix that. Also had to do a lot of tweaking in XBMC and especially Boxee to output sound over HDMI.
I’m somewhat familiar with XBMC, but I’ve wanted to try Boxee for awhile now. It’s supposed to be more user-friendly than XBMC, offering a simplified interface based on the XBMC code. It also has that whole “social media” aspect, whatever that’s about. Its real attraction is the user-friendliness; I hate having to do so much manual configuration in XBMC. I need something that my wife and I can just pick up and use; no hassle, no tinkering.
Initial XBMC impressions
It works somewhat better than the version I used several months ago. However, most of the video plugins are buggy and/or completely broken, as are some of the helper programs and utilities. All that’s supposed to change, though, with the next XBMC release. Supposedly there’s an entirely new architecture, so maybe I’ll finally get to watch my favorite shows and stream local media a bit easier, with better content scraper integration.
There are some things that don’t work — nothing on SyFy, and all too often the existing network TV plugins don’t work for all advertised shows. Mythbusters in particular is very buggy, offering only partial listings for 5 or 6 seasons, and those are extremely low-quality Flash streamed from some third-party download site. Still, my wife can watch her crime shows and 80s favorites, while I can get a fair amount of Mythbusters and other Discovery shows.
Initial Boxee impressions
Useless. Slow. Hard to configure. Totally not what I thought it’d be like. Boxee didn’t offer any of the easy internet TV watching I thought it’d have, instead offering a couple hundred useless channels for things I’ve never heard of. I expected it to have better integration with regular network TV, the same ones I can watch in a web browser. I expected a nice presentation of content, with the video wrapped in a full-screen Boxee experience. I expected hi-def streaming content; instead, the few shows I’m interested in are only available in stuttering low-quality Flash. Why bother, when I can watch The Guild in gorgeous 1080p on my Xbox?
At least XBMC has somewhat working plugins for several networks. Apparently XBMC plugins don’t work that well (or at all) on Boxee. I gave up trying to make ‘em work. All too often the shows are streamed from stuttering, blocky Flash videos. I tried using the integrated Boxee web browser to watch things like Hulu, but that turned out to be an even slower, laggier disaster.
On the hardware side, it was harder to get HDMI sound working on Boxee than on XBMC. And even though I have all the right VDPAU libraries installed, and I’m using the latest nVidia driver (195.x), nothing on Boxee seems to be accelerated. Even 720p content streamed from my LAN stutters, with the audio occasionally lagging the video. XBMC doesn’t have this problem, so I know it’s not the graphics stack.
Boxee is definitely beta. Maybe everything will work fantastically on the Boxee Box, but I don’t want to spend another $200+ dollars on essentially the exact same hardware. I want to like Boxee, I really do. But at this point, XBMC works where Boxee fails, and even though its user interface is more cumbersome, it still lets me watch videos and play music.
Initial Ubuntu impressions
Slick. Very slick. Installation from a USB key went very well. While I tried to do everything from the commandline in Gentoo, using syslinux and whatnot, none of the Ubuntu guides on creating LiveUSB media worked. I ended up just compiling Unetbootin and Qt4 on my Xfce laptop. Unetbootin worked perfectly on the first time, giving me a bootable 4GB USB stick loaded with Ubuntu 10.04.1.
Installation was simple and straightforward, with minimal user interaction. I did a bit more, because I wanted to create a custom partition layout, but otherwise the end-user part of the process was done in just a minute. The rest of the install proceeded automatically, booting me into a bright, shiny Gnome desktop. After a minute or so a few notifications popped up, advising me to install the proprietary nVidia driver and install some software updates. That took just a couple of clicks. Sweet! Oh, the joys of binary package management.
Even though the HTPC only runs a lowly 1.6ghz dual-core Atom chip with a mere 2GB RAM, the desktop still feels pretty responsive. Firefox starts up as fast or faster than my 1.5ghz Core2Duo laptop with twice the RAM. In my experience, Gnome is always pretty heavy, feeling fairly clunky and somewhat slow even when backed by speedy CPUs and gobs of RAM. Nautilus and Evolution windows always seem to load much slower than Thunar and Claws Mail, or even PCManFM and Thunderbird. Still, despite the anemic hardware, my Gnome experience in Ubuntu is surprisingly pleasant. Nothing seems particularly slow to start on a fresh login. The boot process itself could be faster, though; it takes more’n'a minute to get logged in. I need to cut that down to 10 seconds or less to get a true HTPC “instant-on” experience.
There are some quirks in most ION devices related to suspend and USB wakeups, and my Zotac MAG is no exception. I need to do some commandline hacking to get the computer to suspend every time, and to wake only when a button is pushed on the remote. And configuring LIRC is a whole ‘nother deal.
But still, I’m liking what I see. Ubuntu 10.10 will be released next month, and it promises even more improvements and nifty app integration than 10.04.
In fact, I liked my brief experience with Ubuntu 10.04 enough to download a daily LiveCD beta of 10.10, “Maverick Meerkat.” I plan to create a LiveUSB and install it on my “Linux playground” partition. I’ve gotten just a taste of how Ubuntu works when using it as a special-purpose media center; now I want to see how it works as a mobile desktop OS.
The last time I had Ubuntu on my laptop, it was Ubuntu Studio 8.04 a few years ago. It lacked polish, lacked the cohesive desktop experience Ubuntu is known for. Its sole advantages were that it was optimized for media production, featuring a low-latency kernel and tons of preinstalled music software, with easy access to much more. I experienced numerous issues with JACK and my USB-to-MIDI adapter, though, so my plans for tinkering with music were shelved.
I’ll see how vanilla Ubuntu works on my laptop, and if it goes well, I may look into converting it into a low-latency/realtime audio production environment. I’m very interested in being able to quickly, easily use this machine to create tunes and link up with my piano. There’s been a lot of progress in the Linux audio world in two years.
I turned my Gentoo install into a bleeding-edge hardmasked/~arch/stable Xfce testbed. I decided to dump HAL and setup PolicyKit, ConsoleKit, udisks, upower, udev, that whole stack. Originally I wanted just to try out the experimental PackageKit features for Portage, which was a recent GSoC project. I knew that would require most of the aforementioned software stack, so I thought, “As long as it has to be installed anyway, why not dump HAL, too?”
One thing led to another, and pretty soon I had upgraded to Xserver 1.9, disabled HAL, rebuilt world a few times for USE flag changes, and pretty well screwed my system. Reconfiguring my input devices for
xorg.conf.d took awhile, and I’ve been besieged by other difficulties. That’s the problem with a source-based distro, and the problem of running Xfce in particular: nothing is especially integrated, and in a lighter environment like Xfce (compared to Gnome), there isn’t much code that’s designed for a HAL-less system. Apps written for *Kit/udisks/upower are either only available in git, or still unported. A binary distro like Ubuntu would integrate all that stuff forcibly, by writing their own code if need be, so that various actions that require PolicyKit authentication would pop-up windows, prompting for passwords. None of that happens on my Gentoo system.
I ended up adding the Xfce overlay and adding several hardmasked 4.7/live versions of packages just to get udisks/upower support, which helped some. However, several bits of Xfce and other daily applications just don’t have the right code yet. So xfdesktop doesn’t display icons when drives are plugged, cameras won’t always mount and make their photos available, and not all power management options work, even when the user has the right PolicyKit credentials. That’s on top of having to reconfigure pretty much my entire working environment due to changes between 4.6 and 4.7 — everything from panel applets and their configs, to Thunar and window manager preferences. Despite
USE="sound" installing libcanberra for event support, and adding
sound-theme-freedesktop, event sounds cannot be enabled in the appropriate dialog, because Xfce doesn’t believe libcanberra is installed. It’s the same for Pidgin — it doesn’t believe there’s a working sound framework, either. I have to give it commands like “aplay /some/dir/foo.wav” for each kind of event.
The whole thing, is, quite frankly, a bloody mess. And all because I wanted to get some experimental Portage toys from an overlay. It’s my fault, I admit, and even after 8 hours of hacking at it, I’m probably nowhere near finished, assuming it’s even possible to get all the bleeding-edge pieces to play nicely together.
(Side note: I would like to thank my fellow Gentoo developer Samuli for taking the time to answer my numerous Xfce-related questions and do a bit of troubleshooting along the way. Thanks, man!)
So, what’s to learn from my adventures? First, trying to put everything back to its previous state would take another two days of work, if it’s even possible! Second, the price for living on the bleeding edge of *Kit integration is too high. I don’t mind running the occasional ~arch package, or using git X11 driver stacks like xf86-video-*, Mesa, and libdrm. But basic hardware abstraction stuff is nothing to be fooling around with. Not being able to use pluggable devices, enable Bluetooth, or properly adjust power management on a laptop is too high a price for being forward-thinking. I wish I’d stayed with my boring HAL system. While deprecated and a pain to configure, at least it worked reliably. More important, maintenance was nonexistent; it was simply a matter of copying several
.fdi files into the right directory when I first compiled and installed my desktop. After that, I didn’t have to touch a thing.
The HAL-less desktop is supposed to be the future for every Linux distribution out there. I can only hope it is still some ways off, to give upstream coders more time to get their applications in order, so that distributions don’t have to do much patching or extensive repackaging and integration, and so that the end-users don’t have to spend hours configuring everything to their liking.
