 |
|
Hi I am currently tyring to downgrade my nvidia drivers from the 81xx drivers to an older version, this is becuase of problems with a known cedega/nvidia incompatability with the 81xx drivers.... anyhow i have followed the gentoo documentation on how to install nvidia drivers to the letter and when i run
| Code: | | glxinfo | grep direct |
i get the following output (also xorg wont start when i reboot)
| Code: | Error: API mismatch: the NVIDIA kernel module is version 1.0.8178, but
this library is version 1.0.7676. Please be sure that your kernel
module and all NVIDIA driver files have the same driver version.
Error: glXMakeCurrent failed |
obviously somthing is still pointing to the old drivers but i am not sure how to change it, i have downgraded nvidia drivers in the past without this problem... Any help would be awesome...
Thanks

| looks like either 1/ you didn't downgrade nvidia-kernel, just nvidia-glx, or 2/ you still have the newer module loaded (perhaps due to downgrading while X was running?) |

It looks like you've unmasked nvidia-kernel but not nvidia-glx - both need to be unmasked and at the same version (but not necessarily the same revision).

i am sure that i have downgraded both nvidia-kernel and nvidia-glx
| Code: | media-video/nvidia-glx
selected: 1.0.8178
protected: 1.0.7676-r2
omitted: none
>>> 'Selected' packages are slated for removal.
>>> 'Protected' and 'omitted' packages will not be removed. |
| Code: | media-video/nvidia-kernel
selected: 1.0.8178-r3
protected: 1.0.7676-r1
omitted: none
>>> 'Selected' packages are slated for removal.
>>> 'Protected' and 'omitted' packages will not be removed. |
after doing this process i run the commands
| Code: |
# modprobe nvidia
# modules-update
|
and i also have tried the command
| Code: | | # opengl-update nvidia |
with no success
and also i do not have any mention of nvidia-kernel or glx in my package.unmask or package.mask files....
I did do this process while X was running i also did it when it was not running it didn't make a difference. Shouldn't a reboot fix this problem if its just the wrong module running? It still doesn't work after a reboot....
