Howto: Not have Nouveau kernel module take over nVidia drivers

June 21st, 2010 Quail No comments

Since the last Debian testing kernel (2.6.32.5) update, I have rebooted and found myself being in what seems to be a kernel issue, where by a module “nouveau” by default seized control of the graphics card which prevents the nVidia driver from loading and would not allow me to compile and install the nVidia proprietary driver either. I also didn’t not have “xserver-xorg-video-nouveau” installed.

Here is the work around I used to resolve the problem.

If you use grub2 then edit

/etc/default/grub

then add

nouveau.modeset=0

to the end of the line that reads

GRUB_CMDLINE_LINUX_DEFAULT=”quiet”

(“quiet” seems a typical default option), so that that line now reads

GRUB_CMDLINE_LINUX_DEFAULT=”quiet nouveau.modeset=0″

run

update-grub2

and reboot.

Now go through and install you nVidia drivers as per normal.

Gnome System Monitor causes Xorg to consume 100% CPU

April 29th, 2008 Quail 1 comment

With Gnome System Monitor 2.22 under Debian testing (Lenny) I had the problem when I clicked on the Resources tab the CPU usage would got to 100% on my laptop and desktop.

Well I have been able to fix the problem on my laptop which has and Intel video card by adding Option “AccelMethod” “EXA” to the Device section in my xorg.conf file.

Example:

Section "Device"
        Identifier      "Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller"
        Driver          "intel"
        BusID           "PCI:0:2:0"
        Option           "AccelMethod"  "EXA"
EndSection

When I have worked out how to fix the problem on my desktop using a Nvidia video card I will post the solution.

Thanks goes out to MistaED for pointing out to me that this a problem with the way Cairo rendering is done.
