I am not able to apply the patch provided in the gdev/mod/patches to linux-2.6. So I manually patched linux-3.5.0 with the given nouveau patch. When I insert the gdev module I get module insertion error.

Any ideas where am I going wrong.

The 3.5.0 patch has not been well tested. For this moment, please use Linux 3.3.0 kernel and mod/nouveau-3.3.0

That was probably a bug when the patch file was initially generated.

For this moment, do not use the patch file. Use the already patched nouveau source residing in /mod/nouveau-3.3.0. Compile, install, and use it. It should work then.

Of course, make a fresh compilation and installation of linux-3.3 first

I installed linux-3.3 and then the compilation went trough.

I checked that the nouveau module is installed properly

root@WhiteRose:~/gdev/mod/build# lsmod | grep nouv

But during the insertion of gdev module I get the following error

Did you blacklist the nouveau module bundled with linux-3.3? You have to do that and boot into level 3; then load the nouveau bundled with gdev, and compile/load gdev

Thanks for the prompt reply. Yes I had not blacklisted the default nouveau. I will try it tomorrow as currently I don't have physical access to the system.

I blacklisted nouveau installed the one with gdev, but when i try test the nouveau installation the kernel crashes. So I tried installing pscnv. Whey i try inserting the gdev module it says undefined symbol error. I checked for those symbols in pscnv they are present.

gdev module insertion error:

I blacklisted nouveau installed the one with gdev, but when i try test the nouveau installation the kernel crashes. So I tried installing pscnv. Whey i try inserting the gdev module it says undefined symbol error. I checked for those symbols in pscnv they are present.

gdev module insertion error:

What is your machine environment?
I would recommend nouveau. Can you explain how your kernel crashed?

I blacklisted nouveau installed the one with gdev, but when i try test the nouveau installation the kernel crashes. So I tried installing pscnv. Whey i try inserting the gdev module it says undefined symbol error. I checked for those symbols in pscnv they are present.

System Details
GeForce GT 420
Linux -3.3.0

4GB RAM

modprobe nouveau modeset=1 noaccel=0
crashes my kernel
It works without the extra parameters (modprobe nouveau) but in dmesg I find unknown symbol error.

Thanks,

I'm a bit worried about GT 420 as this series is the most tricky architecture in Fermi AFAIK, though it should work with Gdev by now.
You need "modeset=1 noaccel=0" to enable GPU acceleration with Nouveau.
Can you try to install vanilla Nouveau with "modeset=1 noaccel=0" parameters?
If this doesn't cause your system to crash, it means Gdev has some bug to set up GT 420.
