i915.ko causes my Debian Lenny to sleep


Hi Guys,
Please be patient with me :-) I do know some things but definitely not everything.

I have Debian Lenny running on my new desktop.
Every few times I try to boot it up it goes to sleep as soon as it gets to the part where Xwindows should load.

I have spent hours looking for the fix for this and found a link that says disable i915.

So I have renamed my i915.ko file to be i915.ko.hold and great news it seems to be fixed.

The thing is I am a bit of a perfectionist..... What does this actually mean I have done? Is this file only used to give better performance to my video? Why does my system seem to be working perfectly without this file if it is needed. Am I just using a lesser quality video now?

Thanks in advance for any advice on this.

Larry

i915 (e.g. /lib/modules/2.6.18-164.el5/kernel/drivers/char/drm/i915.ko)
is (as drm signifies) responsible for providing DIRECT graphics rendering.
Your X.Org installation will now have to fallback to indirect (i.e., software) rendering of 3D output, thus 3D operation will be slower.
Running glxgears might indicate this. And glxinfo output will list "indirect" rendering I'd assume.

Thanks for this helpful reply :-)

I still don't know why this particular module causes my system to sleep, so if anyone else has insight into this problem, I would be happy to try and re-instate it if this is possible.

For anyone who has the knowledge to understand this information ( I do not have this knowledge) I offer the following details of my system...

v02.61 1985 - 2009, American Megatrends, Inc
Intel Core(TM)2 Duo CPU E7500 (2.93GHz)
2048MB of ram
Bios version 0313
Build date 07/03/09

I have not changed any of the cmos settings except for the automatic start on power up.

I am running Debian Lenny with standard kernel 2.6.26-2-686

I have a LG Flatron L1752T monitor and I am using the standard 15 pin D shaped connector system for my video cable.

I have my resolution set to 1280 x 960
refresh rate at 60HZ

Once, again, thank you for being here for me and others like me :-)

Regards
Larry
