[prosavage8] Only root can start X at a reasonable resolution

[Norbert Bollow]

Binary package hint: xorg

After upgrading from 10.04 to 10.10 on 2010-10-29, I've experienced the following show-stopper a problem: I'm using gdm. However, upon entering the correct password at gdm, the screen blinks and the gdm login screen is built up again.

In order to start investigating the problem, I have booted into "recovery mode" from the grub menu, then chosen "netroot" in the Reciovery menu.

If I type 'startx' as root, it works.

If I 'su - nb' first, the type 'startx', the screen goes dark with an "Input Not Supported" box from the monitor.

The Xorg log file from the case that doesn't work (attached) is very similar to the case that does work.

The only possibly-significant difference is the final line

[ 2295.773] (--) SAVAGE(0): Chose mode 14f at 85Hz.

which doesn't have an equivalent in the Xorg log file for the case that works.

I'm using the SAVAGE driver, but the problem is not specific to this driver: It occurs also when forcing use of the VESA driver.

Through manual xorg.conf configuration it is possible to create a configuration which allows successfully starting Xorg by running 'startx' as a non-root user, although at an unacceptably low resolution.

The problem is not specific to Ubuntu: It also occurs with Arch Linux 10.05

I have a fresh install of Ubuntu 10.04 (which does not exhibit the problem) now which I'm using for reporting this issue. So the automatically provided information from the 'ubuntu-bug' script should be referred to only for information on the hardware where the problem occurs.

Can you try deleting your .config/monitors.xml file?

Hey Norbert,

Hi, have you had a chance to test if this bug is still present in natty?

If it does (and if you're the original reporter), please boot into natty
and run the command:

  apport-collect <bug-number>

which will update the bug with fresh logs and tag the bug as affecting
natty. (It is best to run this right after reproducing the problem.)

Ubuntu 11.04 (natty) reached end-of-life on October 28, 2012.
Ubuntu 10.10 (maverick) reached end-of-life on April 10, 2012.
Ubuntu 10.04 (lucid) reached end-of-life on May 9, 2013.

This bug report refers to releases which have been 'end of life'
for many years now. It did not expire due to assignment.

There was no reply to comment #3 made over 11 years ago so closing
this now as being 'Invalid'.
