Lenovo i915GM=very slow 2D

Hi.
I need advice or suggestion.
I have Lenovo 3000 C100 with i915GM video.

I use XFCE.

Xorg.conf:
Section “Device”
BoardName “915 GM”
Driver “intel”
Identifier “Device[0]”
Option “monitor-LVDS” “Monitor[0]”
Screen 0
VendorName “Intel”
EndSection

uname -a:
Linux linux-m3e1 2.6.27.19-3.2-pae #1 SMP 2009-02-25 15:40:44 +0100 i686 i686 i386 GNU/Linux

Question:
Every scrolling in every window makes X use up to 70% CPU.
Xterm window - very slow.
It has enough Video memory to keep text from one xterm window.
Where is 2D rendering? Look like all text goes from base memory, but not from video memory, video card does not cache anything.
I do not talk about 2D acceleration - I just need normal 2D rendering. 915GM - is not new card and it should work already.

So, how to improve it ???

Thanks.

I have a T61 with a 965GM Intel - performance is horrible. Was great in openSUSE 11.0. Anyone know if an updated xorg will do the trick or if I have to wait for Intel to fix the drivers?

Hi,

I have reported a bug at Novell Bugzilla site because my problems with Intel 965 GM graphics card. As toharris said, this card just works wonderfully in openSUSE 11.0. Unfortunately, in openSUSE 11.1 it is complete messy.

According to a guy that replied the bug report (https://bugzilla.novell.com/show_bug.cgi?id=480713), we have to wait for new Mesa packages. This packages have the drivers for Intel graphic cards and they will be included in a 11.1 update that will be available soon. (I hope so! :slight_smile:

Well, good luck for every one who have Intel cards.
