My general advice: do not trust ONLY this message. The real error is elsewhere. For instance, I wanted to post to proxas.free.adsl, and until wireshark gave the me the answer, I lost 2 hours searching on the net...
Trust me: wireshark the communication. For me the answer was: POST Yes! Just because I was in UTF-8 charset... Lundi, 17 octobre 2011

NOUVEAU fails now systematically after each reboot. Why ? The Xorg.0.log says "Permission denied" at somewhere near NVEnterVT.
No problem, switching back to NVIDIA for a while, I hope this will get looked at soon. Dimanche, 16 octobre 2011
NOUVEAU driver ready to replace ... Posté par Jean-Damien Durand

The only reason why I did not switched to the NOUVEAU driver up to now was the lack of 3D acceleration. I was not following this issue and did read by chance this mail on another interesting topic (Gnome 3), which was redirecting me to this other mail, giving the status of 3D NOUVEAU acceleration: just install the libgl1-mesa-dri-experimental package!
Gave it a try, and... yes! Okay, you better have a nvidia card supported by the NOUVEAU driver of course: nvidia cards are grouped by Codenames, find yours, and then check the status matrix for you card. Mine is: % lspci|grep VGA i.e. the NV50 family that has quite a good status in the NOUVEAU status matrix. And indeed, glxinfo is happy: % glxinfo|egrep -i "rendering|GLX" confirmed by glxgears, giving a little bit less than 800 FPS. Very well done, developpers. So I removed the NIVIDIA proprietary driver: % apt-get remove --purge nvidia-glx xserver-xorg-video-nvidia libgl1-nvidia-glx nvidia-alternative libgl1-nvidia-alternatives nvidia-kernel-dkms nvidia-settings nvidia-vdpau-driver nvidia-xconfig, installed the NOUVEAU driver: % apt-get -t unstable install libgl1-mesa-dri-experimental xserver-xorg-video-nouveau, remove my hacked xorg.conf that was: Section "ServerFlags", rebooted, and it works. Again many thanks to the NOUVEAU developpers. This is simply a great and professional work. PS: do not remove APIC when you boot linux, I am a noob in kernel knowledge, but indeed this was an error (I was playing with various settings on my realtime version of the kernel). And the "noapic" option was a leftover from this (more precisely, I was playing with the IRQ interrupts!). The NOUVEAU driver failed first, saying: "(EE) NOUVEAU(0): failed to set mode: Device or resource busy"... Removing the "noapic" from the kernel boot options was enough to get NOUVEAU driver back to life Samedi, 15 octobre 2011

Wanting to give a try on the archlinux linux-rt kernel, but on debian? The pkgbuild scripts are easy to understand, and here is a translation of the linux-rt pkgbuild on debian:
#!/bin/sh Package uploaded to: deb http://jeandamiendurand.free.fr/debian/kernel sid main Note: as usual nvidia and rt patches are not friend, you'd better use the NOUVEAU driver (which is getting better and better btw, don't you think) Well, this should have been linux-3.0.6-rt17 really, never mind |
