Debian Lenny (and fully working X in Linux) — I'm back

I've written hundreds of posts about Debian, and maybe just as many about trouble I've had with my Intel-graphics-using laptops and screen artifacts in the X Window System graphical environment for Unix/Linux operating systems.

Now I've got a fresh, working Debian Lenny installation on a test machine and have solved the artifacts-in-X problem that has plagued me in Slackware and Debian (and a few other distros that escape me) for probably a year or more.

One of the hardest things I ever did in my Unix/Linux journey was give up Debian Lenny back in its Testing days when I couldn't solve the screen-artifact problem.

I worked for weeks, maybe months, hacking away at the problem, tweaking /etc/X11/xorg.conf any number of ways. But I could never solve it.

Among all the Linux distros I tried at the time (roughly all of 2008), only Ubuntu, it seems, was free of screen artifacts. And it was running without an xorg.conf.

Point of order: The screen-artifacts problem wasn't always a problem. I ran numerous distros on laptops with this Intel graphics chip in 2007, and it never happened. Debian Etch, CentOS 5, many, many Puppy Linuxes, Damn Small Linux, PCLinuxOS, Fedora. At one point in Debian Lenny's development, it started to happen. My conclusion at this point is that changes in Xorg, not in the OS itself, are responsible for the problem.

Further point of order: OpenBSD 4.4 also didn't have this problem. I wasn't so lucky in OpenBSD 4.5, where quitting X causes a segmentation fault and core dump. And the xorg.conf I generated with Xorg -configure in 4.5 crashed X entirely. To run it at all, I needed to use the xorg.conf I generated in the same way in 4.4. I don't think it's using the new intel driver in 4.5 vs. the old i810 driver in 4.4, but it very well could be.

Back to X artifacts in Linux: To attack/potentially solve the problem this time, instead of Googling my laptops' names (Gateway Solo 1450 or Toshiba 1100-S101) I instead Googled X artifacts and the graphics chip's name (which I got from running dmesg in a terminal), which is the Intel Corporation 82830 CGC.

I came up with this page from the Arch Linux forums, which gave this advice:

had this exact same problem. put:

Option          "AccelMethod"   "XAA"

into your xorg.conf in the Device section. should fix it!

That worked. After literally hundreds of changes in my own xorg.conf files on a half-dozen or more installs, adding this line to/etc/X11/xorg.conf in Debian Lenny solved my video-artifacts problem.

For me, this is huge. It's my Linux/Unix tip of the year for 2009. Even though there are still seven months left in the year, no tip can trump this one in my own personal FOSS world.

Back to Lenny: A full how-I-installed-Lenny post is forthcoming, but right now I'm in a test environment and will probably change a few things before I nail the tutorial down.

This time at least, I started with a minimal install of Etch and a Half (I'm having CD-reading issues with the Toshiba, and this is the only Debian CD it'll boot from; and I'm also having networking issues with Debian install CDs that are particular to the local network through which I connect to the Internet).

After the minimal install was done from the CD, I then upgraded (aptitude update, then aptitude upgrade, both at a root prompt), added Xfce and a few apps, then changed all references from Etch to Lenny in /etc/apt/sources.list, dist-upgraded to Lenny, added a Lenny kernel (the system didn't do this automatically), did another dist-upgrade, added some more apps, and got Flash and Java working in Iceweasel (the non-branded Debian build of Firefox).

Now I have a working machine that's doesn't quite sip memory like my identically configured (but now written-over) OpenBSD installation but is both faster than my favorite BSD as well as Ubuntu (yes, I know GNOME vs. Xfce isn't a fair fight).

Here's roughly what I have installed on the Lenny laptop:

OpenOffice 2.4
Iceweasel (Firefox w/o copyrighted names or graphics)
Icedove (Thunderbird w/o copyrighted names or graphics)
sudo (I consider it an essential utility, even on systems whose names aren't Ubuntu)
xfce4
xfce4-goodies
2.6.26 Lenny kernel
mtpaint (I'll get around to the GIMP at some point, but this small image editor does most of what I need)
Flash 10 (I used the .deb package from Adobe)
Java in Iceweasel (after adding contrib non-free to the repositories in /etc/apt/sources.list, I added the sun-java6-plugin)
CUPS
xpdf
menus (so I could use update-menus in the console)
GDM (makes it easier to run multiple window managers; unfortunately there's nothing in Debian like Slackware's excellent xwmconfig console utility)

I don't have the networkmanager app that usually runs in standard Debian with GNOME (and with every form of Ubuntu). I re-learned how to manage the network with config files (a lot different than in OpenBSD, that's for sure) and all network-manager-gnome did was screw things up — I couldn't get to it.

Either I'll get deeper into manual configuration in Linux (likely) and get a couple of NICs set up (wired and wireless), or I'll either figure out how to get the GNOME network manager to install (not as likely) or do a "standard" Debian desktop with GNOME and then add Xfce the next time I do an install (could happen).

As I and others have written before, Xfce in Debian is a whole lot lighter desktop than it is in Xubuntu. It's a bit harder to manage, but after the aforementioned six months using OpenBSD, I'm accustomed enough to using the terminal that I'm very happy to use Debian's excellent aptitude in the console/terminal to update and add/remove applications and really don't need Synaptic (which I could easily add).

As I also mention above, I started with the minimal install because I had problems with networking in the Debian installer (my network's problems, not Debian's), but the next time I do this, I'll probably select Xfce as my desktop either in the installer menu itself (if I can get a Lenny disc to boot) or at the boot line in the Etch and a Half installer (desktop=xfce, I believe the line is). My goal is to find a Lenny install disc (possibly the entire "disc 1" of either the GNOME or Xfce builds ...) that the Toshiba 1100-S101 will boot from. I've made them on various PCs and Macs, and it's hit or miss. The Toshiba will read the CDs, it just won't always (OK, will only seldom) boot from them.

Just to get all the GUI tools you might want in a pinch, it's probably a good idea to start with the "standard" GNOME desktop, but in this case I wanted to save disk space and keep the system lean.

As nice as it is to have Lenny back on one of my desktop systems (I haven't yet made the decision to replace Ubuntu 8.04 on my main production system, and despite all philosophical rants to the contrary, I'm sticking with it at present), it's even nicer to solve that X-artifacts problem that has kept me from using so many good systems for so long.
