mandrake 10.1 GLX problem

mewgle · 03-12-2005, 03:32 PM

Hello,
I have just installed Mandrake 10.1 on my laptop with an NVIDIA GeForce4 448 go, and installed the nvidia drivers from their website. It works in the sense that the NV logo shows up when logging in. But, glxinfo | grep direct returns

Code:

Error: Could not open /dev/nvidiactl because the permissions
are too resticitive.  Please see the FREQUENTLY ASKED QUESTIONS
section of /usr/share/doc/NVIDIA_GLX-1.0/README for steps
to correct.

My XF86Config file is:

Sorry for the long post, but I am not sure how else to post this.

Thanks in advance for your help.

Does anybody know?

i don't know about mandrake but this might help
it's what i did anyway (might help you troubleshoot)
first wherever is a file you load modules at boot there put nvidia if it's not already
then
look for a folder like (mine is) /etc/udev/permissions.d
in there should be a few files
start with the one with the lowest numbers and see if there is a section about the video devices
i put for mine

Code:

agpgart:root:video:0660
nvidia[0-9]*:root:video:0660
nvidiactl:root:video:0660

660 is rw-rw----
don't change yours if it's similar and if it's not there look in the other files first i think before adding
if you change things of course make backups of the changed files

ok -- for me this results in at boot udev creats
cd /dev
ls -l | grep nvidia
crw-rw---- 1 root video 195, 0 2005-03-12 09:53 nvidia0
crw-rw---- 1 root video 195, 255 2005-03-12 09:53 nvidiactl

ok - so the group "video" for me has read write permissions on the device
so in /etc/group
i add myself "user" to the end of the video group line
video:x:12:user
log all the way out and back in and it worked

Thanks for the reply. The output of ls -l | grep was identical to yours. As far as your suggestion with /etc/group im not too sure what exactly to do.

Here is what it says in /etc/group:

Code:

root:x:0:
bin:x:1:
daemon:x:2:messagebus
sys:x:3:
adm:x:4:
tty:x:5:
disk:x:6:
lp:x:7:

My username for mdk is mog by the way.
I am still a linux

Ok, i reread what you wrote and figured that you just added the username to the end of the video: line and it works now. Thank you for your help..
