Hello,
I’ve recently had to switch from Nouveau drivers to Nvidia drivers because KDM dies on login (possibly due to an update I recently download…)
Now KDM runs with the Nvidia drivers, but the interface is slow – for instance, with 5 windows open, Yast takes a full 3-4 seconds
to refresh a window. Resource use by Xorg is also extremely high - up to 80% of CPU just for switching between windows. BTW this is with all special UI effects turned OFF.
I’ve looked around forums on the internet and tried a couple of things but nothing seems to work.
Sorry if I providing too much system information – I freely admit I’m not trained in IT, am relatively new to Linux, and am but a lowly electrical engineer, not a Computer Science graduate.
Thanks in advance.
My system information:
I am running OpenSuse 12.1.
rpm -qa | grep susesusehelp_en-2009.10.06-11.1.1.noarch
susehelp-2009.10.06-11.1.1.noarch
opensuse-manuals_en-12.1-12.3.2.noarch
libksuseinstall1-4.7.2-5.2.2.x86_64
susegreeter-branding-openSUSE-12.1-15.3.9.noarch
Here is my kernel information:
uname -r
3.1.10-1.9-defaul
As well as what I could glean about the Nvidia card:
Quadro NVS 290
Revision 161
Subvendor Identifier 69854
nVidia Driver Version: 295.48
which I have hooked up to two displays with Xinerama enabled.
x11: version 4 server nv
CPU is an Intel Core2 Quad Q9550 @ 2.83 GHz with 4GB RAM.
