What is Gnome doing with 3D options of a nvidia card? Looks like it does something what is not right ... My problem ... Got a nvidia 9300M videocard and glxgears gives me about 950 fps what is not enough to play cool games like Nexuiz or OpenArena .. Tried lot of xorg.conf options .. also the options on this forum, but nothing help .. always fps around the 900 On other distributions i never had problems ... so did not understand it. Yesterday .. i thought ... lets install KDE ... and looks if it works then. And what do u think ... 4300 fps. AN di can play Nexuiz without any problem. So ... what happend in Kahel if Gnome start up? Already drop compiz, also not any effect. Anybody an idea? joelbryan on "Enable Kernel Mode Switch (KMS) on Intel Graphics Card" http://forum.kahelos.org/topic/enable-kernel-mode-switch-kms-on-intel-graphics-card#post-57 Wed, 23 Sep 2009 13:18:39 +0000 joelbryan 57@http://forum.kahelos.org/ KMS is the next generation graphics infrastructure that improves the overall video 3D graphics performance and allow to use the latest DRI2 (Direct Rendering Infrastructure 2). To enable KMS on Intel Graphics Card on Kahel OS, do the following. 1. Synchronize your System with the latest Kernel. <code>sudo pacman -Syy && sudo pacman -Syu</code> 2. Remove existing graphics subsystem to avoid conflict. <code>sudo pacman -Rd dri2proto intel-dri libdrm mesa xf86-video-intel</code> 3. Compile and install the latest GIT-version of Intel drivers and 3D graphics systems using 'yaourt'. <code>yaourt -S --noconfirm aur/dri2proto-git</code> <code>yaourt -S --noconfirm aur/glproto-git</code> <code>yaourt -S --noconfirm aur/intel-dri-git</code> <code>yaourt -S --noconfirm aur/libdrm-git</code> <code>yaourt -S --noconfirm aur/mesa-git</code> <code>yaourt -S --noconfirm aur/xf86-video-intel-git</code> 4. When all goes well, remove existing xorg-video-drivers <code>sudo pacman -Rssuuvvcc xorg-video-drivers</code> 5. Create a file named 'intel-kms.conf' in /etc/modprobe.d/intel-kms.conf by <code>sudo nano /etc/modprobe.d/intel-kms.conf</code> Then add the lines, then save. <code>options i915 modeset=1</code> 6. Edit the file /etc/mkinitcpio.conf and add the 'intel_agp i915' line in the MODULES list. <code>sudo nano /etc/mkinitcpio.conf</code> then add 'intel_agp i915' at the very start of the MODULES=(...) list, so the line <code>MODULES=(crc32c ...)</code> will become <code>MODULES=(intel_agp i915 crc32c ...)</code> 7. Include the file '/etc/modprobe.d/intel-kms.conf' in /etc/mkinitcpio.conf FILES list, so the line <code>FILES=""</code> will become `FILES="/etc/modprobe.d/intel-kms.conf" Then save. 8. Add 'intel_agp i915' in /etc/rc.conf <code>sudo nano /etc/rc.conf</code> then the line <code>MODULES=(fuse usblp)</code> will become <code>MODULES=(fuse usblp intel_agp i915)</code> then save. 9. Generate a new kernel. <code>sudo mkinitpcio -p kernel26</code> 10. Then reboot. TROUBLESHOOTING If you see a message "error inserting i915.." you may have to regenerate your kernel again prior to the reboot and installation of the new kernel and drivers.
