cannot login after upgrading to kde 4.3.3... low graphics mode...

[kxmas]

OK, I just try at work with an Intel IGP on a system without gdm and instead of showing the recovery menu it just show a black screen and cut the screen power

Rebooting in recovery mode I remark the following in kdm.log:
X: /tmp/.X11-unix has suspicious mode (not 1777) or is not a directory, aborting.

So I remove all files in /tmp and reboot. And now all is working fine
I rebooted 3 time straight to the kdm login screen without problem.

Interesting. I shall try this after work and report my results here.

There's an extra twist to this story as some of us can't even read the "low graphics mode" pop-up as the wrong resolution is selected and all you can see is mush!

Rolling back the X updates (post #19 of bug report https://bugs.launchpad.net/ubuntu/+s...3?comments=all) got my system working again using KDM.

I got the same issue after upgrading to kde 4.3.4. I upgraded to kde 4.3.3 before without any problem. Switching to gdm solved it to me. Do you know if there is a bug report about this?

Don't ask me why, but the following steps helped to solve the problem on my Kubuntu Karmic Koala with KDE 4.3.3:

1. copy /etc/init/gdm.conf to a place as you like (backup)
2. delete /etc/init/gdm.conf
3. Restart Kubuntu

Apperantly, gdm an kdm are conflicting in the boot process through upstart...

Hello,
This problem may be related to another bug, that is causing kdm to attempt to start twice. The first time it tries to start is in failsafe mode, before the video driver is loaded, hence the "Low Graphics" error.

Try the following as a workaround:

cd /etc/init
sudo mv failsafe-x.conf failsafe-x.conf-disable
cd /etc/init.d
sudo mv failsafe-x failsafe-x-disable

See if this gets kdm going (works here).

I got it working doing something similar.

1. Change the driver from 'vesa' to your actual driver in /etc/X11/xorg.conf.failsafe. Failsafe now works with intel. Big improvement over the blank screen

2. Create a new /etc/X11/xorg.conf that contains the following, changing intel to the driver that you use

Section "Device"
        Identifier      "Configured Video Device"
        Driver          "intel"
EndSection

3. re-run sudo dpkg-reconfigure kdm and select kdm as your default.
