fglrx + "switch user" scrambles screen on ATI 200M

[Wouter den Haan]

Binary package hint: xorg-driver-fglrx

I am currently using the fglrx driver on Ubuntu 8.10. I installed/selected it using the dialog at 'System' -> 'Administration' -> 'Hardware'.

When switching to a second user on another VT by using the user switch applet it shows the login screen of GDM, but scrambled. Typing the username/password loads Gnome which is similarly scrambled.

Hi wouterdenhaan,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

As requested.

Thank you for reporting this bug about fglrx, however the video card mentioned in this bug report is no longer supported in fglrx. ATI only supports R600 and newer chips. You'll want to focus on using the -ati driver instead for this hardware.
