Tecra 550CDT and Linux

Decided to try Xubuntu given that it's geared toward older machines. I'm trying 6.10.

Install when smoothly, but, as feared, screen resolution sucks and the network card is not being recognized.

For the screen resolution, I tried the trick I used when installing Ubuntu on this machine a while back: I added these 2 lines to the Monitor
section of /etc/X11/xorg.conf:

HorizSync 30-70
VertRefresh 50-140

After rebooting, I had more screen resolution options to choose from but all below 800x600. I'm shooting for 1024x768, which is the max supported by this display, and what I was able to achieve with Ubuntu 5.x.

Tecra 550CDT and Xubuntu

Decided to try Xubuntu given that it's geared toward older machines. I'm trying version 6.10.

Install when smoothly, but, as feared, screen resolution sucks and the network card is not being recognized.

For the screen resolution, I tried the trick I used when installing Ubuntu on this machine a while back: I modified the HorizSync and VertRefresh lines in the Monitor section of /etc/X11/xorg.conf:

HorizSync 30-70
VertRefresh 50-140

After rebooting, I had more screen resolution options to choose from but all below 800x600. I'm shooting for 1024x768, which is the max supported by this display, and what I was able to achieve with Ubuntu 5.x.

Tried making yet another addition to the xorg.conf file suggested in a post on the Ubuntu forums:

Option "UseEdidFreqs" "1"

No luck, with or without the changes to HorizSync and VertRefresh. (By the way, the above post included a neat shortcut for restarting X: Ctrl-Alt-Backspace. Nice.)

Next I tried modifying the xorg.conf file based on notes posted at http://www.physics.adelaide.edu.au/~jwoithe/toshiba-550CDT.html. I started by commenting out the "Option" line I added above and changing the refresh rates:

HorizSync 31.5-48.5
VertRefresh 55-90

No discenrable difference from my first changes to these values.
