Red Hat Bugzilla – Bug 123221
XWindows will not display
Last modified: 2007-11-30 17:10:42 EST
Description of problem:
X starts but nothing is displayed on the screen. This happens both
during installation as well as runtime (accomplished by using the
character mode install.) After installing in character mode and then
trying to start x from a character login virtual terminal, the screen
goes blank after X starts. Moving back the the charcter terminal
(<ctl><alt>F1) shows many error messages such as 'error Failed to
load module "glx" (modules does not exist, 0)'.
Also: 'error opening security policy file /etc/X11/xserver/SecurityPolicy'
'Could not find init font path element unix/:7100, removing from list!'
Hardware was a Dell Inspiron 7500 R450VT with startup reporting an
'ATI RAGE MOBILITY' controller.
Version-Release number of selected component (if applicable):
install from Fedora Core release 1.92 (FC2 Test 3)
from character terminal type: startx
or boot into graphical installation from CD.
Steps to Reproduce:
1.log into character terminal such as the F1 terminal
Created attachment 100225 [details]
Xorg log file from failed system
This is the log file from X trying to start up
This issue was resolved by following the instructions of Peter Yellman
on one of the Fedora threads "ATI Rage Mobility ..." I followed his
suggestion to add "vga=0x31A" at boot time to enable the frame buffer
and it works fine. I have to install in character mode, and then
modify the grub.conf file for the vga argument.
