I have Fedora 8 x86_64 installed on a machine with on board Intel-945GM
video. The xorg-x11-drv-i810 driver has been giving me a lot of
problems: if I use it, I cannot access a text console using
[ctrl-alt-Fn]; the monitor goes into standby with no display. The
console still reponds to typed commands, but nothing is displayed on the
monitor. On return to the X session, the display becomes unstable, and
often dies, and won't let me log back in -- the gdm screen disappears
and the "loading" cursor appears over a black screen, which persists
indefinitely. I then have to change to a text console, log in (blindly)
and initiate a reboot. On reboot, the POST text display is often wildly
off-center unless I power off the machine for several minutes.
I can use the vesa driver instead of the Intel driver, but then power
management doesn't work. DPMS is enabled in the BIOS and in xorg.conf,
but doesn't seem to be recognized by the vsea driver. If I try using
e.g. GoogleEarth with the vesa driver, the X server just crashes.
What can I do to rectify this? Or should I just shit-can the on board
video and get a separate video card?
My experiences with Intel graphics are generally poor, and it's nothing
to do with amd-64 architected CPUs. After some fiddling, I have this
working in my IBM Thinkcentre:
82865G Integrated Graphics Controller
OTOH I was wholly unsuccessful with this in a Dell Optiplex GX270:
82865G Integrated Graphics Device
This does not work well in my HP DC7700 SFF:
82Q963/Q965 Integrated Graphics Controller
I like to run xen-capable CPUs and this adds to the problems. First,
with xen:
I like to use a framebuffer console. It's a while since I tried on the
Dell so we'll ignore that for the moment.
on the Thinkcentre, I boot with no special options for the kernel or
module lines, vga=text-80x60 works for xen, but that's not good enough.
During running init scripts, I load intelfb
09:37 [summer@numbat ~]$ cat /etc/sysconfig/modules/local.modules
#!/bin/sh
for i in intelfb ;do
modprobe $i
done
09:37 [summer@numbat ~]$ grep intelfb /etc/modprobe.conf
options intelfb mode=1280x1024@70
09:38 [summer@numbat ~]$
That gets me a framebuffer on EL5-clone, whether I'm running xen or not.
On the HP, intelfb does not handle the graphics card, only the vesafb
driver does, and that doesn't do framebuffer under xen.
The problems with these are minor compared with what I experienced on
the Dell. Problems varied, and I had several different versions of Linux
installed on it at the same time, SLES, OpenSUSE 10.0, RHEL5 client and
server betas, FC6. I think it worked if I didn't use framebuffer, but if
I did use framebuffer (and I don't think xen was necessarily part of the
mix), then I tended to get video extreme corruption on the text
consoles, and on FC6 X locked up when I switched back.
If a bit of fiddling with intelfb doesn't get results for you, then an
alternative card sounds good to me.
