Hi! I have an old PC with an 845G card. I've been exiled from my very nice
Linux 3.6 kernel by the EOL tag, and I'm treading rough waters with 3.7 and
3.8. I used to boot to a framebuffer console with "video=1024x786M-8@75", I
think, but since I've started using kernel 3.7, I've had to add or remove parts
until I get a usable console. "video=1024x768M" seems to be a safe choice
right now.
At random, on boot or reboot--and regardless of my video= line--my monitor will
go blank and show "Auto Adjust in Progress" for 6-10 seconds. The system isn't
hanging--I can type my crypto password to my blank, auto-adjusting screen and
keep moving--but I wonder if this is good for the monitor. This is common to
every 3.7 and 3.8 kernel I've used, and all was fine for the other kernels I
used on this PC (3.2 up to 3.6.11). In 3.7 kernels, this happened on every
boot, and there was a longer pause on reboots than for a regular boot. In
3.8-rc4, this might happen 3 boots in a row, then do it only once every 3 boots
for a while.
Attached is my boot dmesg, and maybe somebody out there is smart enough to tell
me which problem is the real problem. I certainly don't know! I have another
PC with the same kind of host-bridge-window boot issue and
motherboard-shared-interrupts craziness, but it has 865G Intel video and
therefore shares only 10% of the glitches that the 845G does.
I've contacted the wrong forum, please feel free to point me to the correct
forum. Thanks!
