Red Hat Bugzilla – Bug 241939
intel driver has blinky startup
Last modified: 2008-01-14 05:17:28 EST
Description of problem:
When using the "intel" graphics driver on Intel 915GM the Xserver is always
starting twice before displaying the graphical environment.
Version-Release number of selected component (if applicable):
Fedora 7 Kernel 2.6.21
Steps to Reproduce:
1. install Fedora 7 on a system with Intel 915 integrated graphics card
when starting xorg, the display shortly turns off and on again two times before
loading a graphical screen
X should started with such issue
Using "i810" instead of "intel" resolves the problem but system-config-display
shows an "unknown video card"
Not a kernel bug, changing to correct component. But also likely NOTABUG, just a difference in the driver.
Works great for me, anyhow. :)
I'd suggest attaching your /var/log/Xorg.0.log file when using the intel driver just the same.

Seems to be nothing wrong with the Xorg.0.log. I also noticed difficulties
using compiz together with the "intel" driver.

Tim Behrsin's Xorg log
I see the same behaviour as described.... although I don't think it is loading
two X sessions: I think it is just a problem with bringing the display up.
Sequence of events whenever an X display is loaded using the intel driver:
( 1. text mode )
2. lcd off
3. blank screen
4. lcd off
5. blank screen
6. normal (mouse pointer, etc)
I'm on a Dell Inspiron 9400 with a 945GM. This happens with rhgb, gdm, etc.
I would also like to say that although this is an annoyance for me rather than a
bug. Compiz, 3D games work fine for me - in fact the Intel driver is a great
improvement over i810 in every respect :)
Same happens for me: Dell Latitude X1
00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML
Express Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express
Graphics Controller (rev 03)
Could it have something to do with this line in Xorg.0.log?:
(WW) intel: No matching Device section for instance (BusID PCI:0:2:1) found
This also happens when one switch between to X sessions (ie. Ctrl-Alt-F8 and
back with Ctrl-Alt-F7) - really annoying, as it takes a couple of extra seconds
Yeah, this is an annoying bug. I actually have some fixes for this, but
they're not upstream yet, and probably won't be until 2.3 at the earliest.
Anyway, this is really an RFE since everything should still work, just not as
prettily as it should.
Given that this is really low-priority with F7, and should be fixed upstream
anyway, closing this bug as WONTFIX.
