Description Steve Cleveland 2007-12-14 14:40:51 EST
Description of problem:

On a Dell SX280 with an Intel video card and the i810 driver, X will sometimes
start, but other times just creates a blank screen.  As far as I can tell, Xorg
is running and the log file makes it seem like it's running as well.  This
happens on multiple machines.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.  Boot up the machine, sometimes works, sometimes doesn't.
2.  init 3;sleep 5;init 5
3.  Again, sometimes works, sometimes doesn't
Actual results:

Sometimes Xorg starts and the display comes up.  Sometimes, it just produces a
blank screen.

Expected results:

Additional info:

[root@nulato ~]# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Integrated
Graphics Controller (rev 04)

The display is a Dell 2001FP, using DVI on both ends.

Following a suggestion found on another bug report, I started Xorg without an
xorg.conf files.  I have attached the Xorg.0.log file from that attempt.

FWIW: I can't use the i810 driver anymore since RHEL 5.1 on an IBM SurePOS 565
(specific Point-of-Sale hardware, also with 82915G/GV/910GL), while RHEL 5.0
worked fine!  Starting the X server *always* (at least every time I tried)
results in a blank screen, keyboard/mouse can not be used (e.g. to switch to a
text console), but the X server stays running and the Xorg.0.log file doesn't
show any errors.  The vesa driver works ok.

I have experienced similar behavior with Fedora 9 on my Dell 700m laptop running
the 82852/855GM Integrated Graphics Device as the VGA controller.  Sporadically,
the screen will blank and hard drive starts racing when I log out or just prior
to gdm loading during startup.  The X server always starts fine during bootup,
but the black screen appears when the graphical boot screen switches to the
login screen.

I have encountered this issue up to half the time I login/logout since Fedora 8
(although it seems less frequent in Fedora 9).  I wonder if it is perhaps
related to changing screen resolution?  I saw a recent bug fix for Ubuntu 8.04:

No further hardware enablement updates are planned for RHEL5's X stack.  If this issue is still present in RHEL6, please update the affected product version and reopen this bug.
