Checking graphic driver

English Hardware

Hi guys,

              I want to know how to check for graphic driver that is loaded currently.

thanks in advance.

cmd

lsmod

gives all kernel modules loaded

so the video driver will be listed

on this pc the radeon driver is installed hence

output of cmd

lsmod | grep radeon :-

radeon               1308792  2 
ttm                    92265  1 radeon
drm_kms_helper         52710  1 radeon
drm                   309344  4 radeon,ttm,drm_kms_helper
i2c_algo_bit           13413  1 radeon

OK my PC shows that I am using gma_gfx. How to know if a driver is loaded correctly or not.

4

What is the default location of drivers. I couldn’t find gma_gfx driver in /usr/lib/xorg/modules/drivers but instead I have vesa,fbdev and modesetting in this directory

5

Another method to obtain the information (run as root)

#hwinfo --gfxcard

Could you please post the output of that as well? So far as I know gma_gfx is not a kernel module in itself - gma500_gfx, i915, etc. are.

Kernel video drivers will be in a location similar to

/lib/modules/3.9.4-1-default/kernel/drivers/video/

As for if it is being used by XOrg correctly, look at the contents of /var/log/Xorg.0.log and search for LoadModule. Note that errors in the log are noted with (EE)

When X loads with a graphic driver, it logs salient information to a log file, with location/file-name /var/log/Xorg.0.log

That file should tell all information and more wrt making a reasonable driver loading assessment.

If one wishes to share that information, then its best IMHO to copy the file contents and paste it to the site SUSE Paste, press ‘create’ on that site, and then share the URL/address of the paste that one is provided.

OK thanks for all your replies.

Great - given the output to hwinfo, we can see:

Driver: "gma500"
Driver Modules: "drm"

The driver (kernel module) is the Intel gma500, and XOrg should be using the drm (Direct Rendering Manager) which is what is used for Intel chipsets.

You should be good to go.

As oldcpu mentioned, if needed post your Xorg log to pastebing, etc.

Here is my Xorg.0.log file
