Description jon scsi 2012-04-08 05:47:44 CEST

Description of problem:
This is an outcome problem found from problem 5245.

My box has an internal video chip of:
00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Integrated
Graphics Controller (rev 04)

Normally I expect the Intel i915G video driver to be used, however it's picked the i810 instead. It works, but has reduced functionality and throughput is a snails pace!

Version-Release number of selected component (if applicable):
Acer V3700GX

How reproducible:
very

Steps to Reproduce:
1. boot.iso
2. try it
3.

What's the output of "lspcidrake -v |fgrep Card"?

Also we only have one intel driver, so I think this report is probably invalid.

Thanks Thierry,
wierd, looking at the dri directory you only have a i915, so it should be the one loaded, yet the message at install only spoke about i810, and gave me the impression that was what was loaded?

I shall run the command when next in mageia.

however, in any case there is a visable differance in video response between mageia2 and puppy's wary522, do you have a glxgears package I can run to test further and get a frame rate?

Comment 4 Thierry Vignaud 2012-04-11 08:56:59 CEST

libdri-drivers provide both i915 & i965 drivers That support different generations of Intel chips.
"Card:Intel 810 and later" is what we tag all intel drivers.
Xorg is then configured with the "intel" driver and will load the appropriate 3d driver (i915 or i965)

"urpmf glxgears" is your friend

Also glxgears is _not_ a benchmark.
See http://wiki.cchtml.com/index.php/Glxgears_is_not_a_Benchmark or http://dri.freedesktop.org/wiki/RadeonTroubleshooting#glxgears_is_very_slow

Status: NEW => RESOLVED
Resolution: (none) => INVALID

I know, but it's a good frame-rate comparison tool!
