I am downloaded latest verson installer and installed my ubuntu. But now how can i check it is insalled and using new driver ? Is there any tool or something?
Hi - the easiest way to check to see if the updated driver is working is to try the following:
- lspci -kvnn : the VGA Controller entry should say "Kernel driver in use: i915"
- modinfo i915 | grep filename : this will show you the path to the module.
If the path has entries in it that say "dkms" and "updates" you are using the updated driver.
If it just says /lib/modules/<kernel-version>-<cpu-architecture>/kernel/drivers/gpu/drm/i915/i915.ko
then you are using the module that shipped with your kernel.
If you think you should have the dkms version you should also run: dkms status
Which will report the status of any updated drivers that have been installed (you're interested in the i915 entries)
Here is my output;
modinfo i915 | grep filename
But i have also installed 1.4.0 installer for Fedora 23. How can i use updated driver instead of kernel version?
Also my kernel is 4.5.4-200
Ah, you're on Fedora - we don't update the i915 module on Fedora as the Fedora kernel is updated too frequently for a backport to be practical (or necessary: if you have the most recent kernel, then you have the most recent i915 driver also).
So what you have is any updated user-space components of the graphics stack that were newer on 01.org than they were on F23, and the fedora kernel itself is already providing you with the latest i915 driver.
