you are using vesa for some reason?

[Susan Cragin (susancragin)]

Problem with 3/29 updates.
I have an Acer Ferrari with ATI Mobility Radeon 7000.
My video card no longer works.
I tried updating xorg. No luck.
I tried adding the following to the conf file;
Option "MonitorLayout" "LVDS,AUTO"
which has worked for the past 8 or so of my installs.
No luck.

Feisty does run from the command line. I have done apt-get update, apt-get install, and then apt-get upgrade.
All updates / upgrades are in place.

I'm not very technically proficient, but I'll help if I can.

susancragin: open a new bug, please... against package xserver-xorg-video-ati

[Paul Sladen (sladen)]

Tracked this down. Timo: yes, "vesa" was being used because autodetection was failing. Autodetection was failing because "discover1" (which does the actual PCI-ID matching) was not installed.

This is strange given that:
  paul@katu:~/src/tree/ubuntu.feisty$ grep -r discover1 .
  ./ship: * discover1
  ./live: * discover1 # for X autoconfiguration

so this should be installed by default.

[Timo Aaltonen (tjaalton)]

xserver-xorg Recommends: discover1, so it is installed by default. You have removed it for some reason.

[Colin Watson (cjwatson)]

Paul, what did you use to install this system? AFAIK the installer has always made very sure to install discover1 before installing xserver-xorg.

[Paul Sladen (sladen)]

I'm trying to think back to when I was testing some earlier xorg packages. If xorg got uninstalled at that point, would it have taken 'discover1' with it (if the auto-removal stuff what used).

One key thing, when I did further --purge/reinstall cycles with 'xserver-xorg' to diagnose this, 'apt-get' was not pulling in 'discover1'---I thought it now pulled in Recommends: by default?

[Timo Aaltonen (tjaalton)]

apt-get does not pull in Recommends: packages, aptitude does (at least with the configuration that is used in installer).

[Tollef Fog Heen (tfheen)]

It seems like you have installed, then uninstalled, then reinstalled packages, there's no guarantee that autodetection will work when you have uninstalled the autodetection tools.
