Need linux command for video driver

jacatone · 03-21-2009, 01:55 AM

I installed the nvidia-glx-96 driver using Envy and wanted to make sure it's installed. What's the linux command for your video driver? Thanks.

When asking a question like this you should, at the very least, mention what distro and version number you are using. You should also list exactly how (by posting the commands you used) you installed the driver.

In any case, to see if your nvidia driver is installed and working correctly, just run this from the terminal:

Code:

glxinfo | grep -i direct

It should return an output like this:

Code:

bash-3.1$ glxinfo | grep -i direct
direct rendering: Yes
bash-3.1$

Type glxinfo at a prompt.

You may need to be root.

Type lspci to see your card and other hardware.

use grep to show only the lines your interested in. Like this...

lspci -v | grep VGA

You can also check what rendering is enabled...

glxinfo | grep render

This is what I get:

jacatone@eMax ~ $ glxinfo | grep -i direct
direct rendering: Yes
jacatone@eMax ~ $ glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Software Rasterizer
jacatone@eMax ~ $

Looks like it's working,

you could also look through the list of modules loaded to see the name and confirm it's presence.

ls mod

and lspci

mine looks like this...

Code:

glenn@GamesBox:~$ glxinfo | grep -i direct && glxinfo | grep render && lspci -v | grep VGA && lsmod | grep nvidia
direct rendering: Yes
    GL_EXT_depth_bounds_test, GL_EXT_direct_state_access,
direct rendering: Yes
OpenGL renderer string: GeForce 9800 GT/PCI/SSE2
    GL_NV_depth_buffer_float, GL_NV_conditional_render, GL_NV_depth_clamp,
    GL_NV_vertex_program3, GL_NVX_conditional_render, GL_SGIS_generate_mipmap,
02:00.0 VGA compatible controller: nVidia Corporation Device 0605 (rev a2) (prog-if 00 [VGA controller])
nvidia               8119640  36
i2c_core               34976  1 nvidia

I see the splash screen as x starts each session, that confirms it to me.

You could also check you /etc/X11/xorg.conf file fot the presence of lines like this...

Code:

Section "Device"
    Identifier     "Device0"
    VendorName     "GigaByte"
    BoardName      "GigaByte GeForce 9800gt (GTX+)"
    Driver         "nvidia"  #This is the nvidia driver from nvidia.com
#   Driver	   "nv"   #this is the default Mandriva system driver 
#   Driver         "vesa"    #I keep vesa support for fallback.
Option 	   "DPMS"
    VideoRam	    524288
    Option 	   "RenderAccel" "True"
    
EndSection

A # comments the line, you can easy edit this file from cli to be able to switch between display types.

I googled...

Software Rasterizer nvidia xorg

and it could be something that can be changed in the config file. Check it out.
