 |
|
I am trying to get X windows working on this new Gentoo installation. I have an Intel i5-3450 processor, which does Gen 7 Intel HD graphics 2500. I have been trying to follow the instructions at https://wiki.gentoo.org/wiki/Intel#Kernel and https://wiki.gentoo.org/wiki/Xorg/Guide.
I added
VIDEO_CARDS="intel i965"
to /etc/portage/make.conf
I ran
| Code: | | emerge --ask --changed-use --deep @world |
I followed the instructions at https://wiki.gentoo.org/wiki/Non_root_Xorg
I tried entering "startx" from my normal userid and xorg almost starts, but I get this error:
| Code: | [ 109.813] (EE) AIGLX error: dlopen of /usr/lib64/dri/i965_dri.so failed (/usr/lib64/dri/i965_dri.so: cannot open shared object file: No such file or directory)
[ 109.813] (EE) AIGLX error: unable to load driver i965
|
A listing of the /usr/lib64/dri directory shows that it contains:
crocus_dri.so
i915_dri.so
iris_dri.so
kms_swrast_dri.so
swrast_dri.so
I'm missing i965_dri.so
I tried reinstalling media-libs/mesa. That didn't help.
How do I get /usr/lib64/dri/i965_dri.so created?
Thanks,
Charles Bailey |

I also miss the particular module but I have no problem.
You need to have dbus and elogind running.Do you?
Plz check
| Code: |
grep modeset /var/log/Xorg.0.log
|
You shuld be running the modesetting driver.
What says
?

With a valid ~/.xinitrc file, xorg does indeed start up and run in spite of the error message. However, without /usr/lib64/dri/i965_dri.so I must be missing some functionality.

i965_dri.so was removed from Mesa 22.0 and replaced by crocus_dri.so or iris_dri.so (depending on the chipset) which should load right away.
Without the full log, we can only guess if acceleration is working or not. Sometimes xorg and friends try things in a certain order until a good driver is found. |

Scanning through the Xorg.0.log showed a couple of references to "Iris"
| Code: | [ 407.388] (II) intel: Driver for Intel(R) HD Graphics
[ 407.388] (II) intel: Driver for Intel(R) Iris(TM) Graphics
[ 407.388] (II) intel: Driver for Intel(R) Iris(TM) Pro Graphics
|
so,
I changed /etc/portage/make.conf to
VIDEO_CARDS="intel iris"
I reran | Code: | | emerge --ask --changed-use --deep @world |
and it spun its wheels for a while and reported that there was nothing to do.
Rebooted.
I got the same error message:
| Code: | [ 109.813] (EE) AIGLX error: dlopen of /usr/lib64/dri/i965_dri.so failed (/usr/lib64/dri/i965_dri.so: cannot open shared object file: No such file or directory)
[ 109.813] (EE) AIGLX error: unable to load driver i965
|
I tried copying /usr/lib64/dri/iris_dri.so to /usr/lib64/dri/i965_dri.so.
That gave me
| Code: | [ 407.422] (EE) AIGLX error: i965 does not export required DRI extension
|
I tried copying /usr/lib64/dri/crocus_dri.so to /usr/lib64/dri/i965_dri.so.
Same result.
I wonder why i965_dri.so was removed from Mesa 22.0? Is this version of Intel HD graphics no longer supported?

One possible thing is that what depend on i965_dri.so have not upgrade to the abandon of it by Mesa. Using the modesetting Xorg module workaround this problem. There is discussion between modesetting and intel Xorg modules and their occuracy and I thing that this discussion can expand to nouveau and radeon Xorg modules.
In practice I see no real difference between modesetting and intel except some FPS differences but the intel Xorg module have more options for configuration. I still use intel and both. Ok I get i965_dri.so on Debian and Arch. Package
libgl1-mesa-dri on Debian and from the mesa-amber package on Arch.

| In short, Mesa removed the "classic dri drivers", so for your Intel gfx you have to move from i965 driver to crocus or iris (which happens automatically once you switch the xorg.conf driver from "intel" to "modesetting"). |

I had the same problem and the same references to Iris.
I solved the porblem by adding in: /etc/X11/xorg.conf.d/20-intel.conf: Option "DRI" "iris"
| Code: |
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "DRI" "iris"
EndSection
|
Thanks

Thanks, rich76, for your response. I tried that 20-intel.conf file and xorg seems to run better now.
(And, sorry for my late reply. I noticed that you posted that on June 9. That was the day I was mauled and severely injured by some big dogs that had been turned loose in my neighborhood and have been recovering ever since. Just now getting back to gentoo.)
