hardware acceleration not working[solved]

[Adel Ahmed]

I have just finished installing gentoo with icewm, but it seems I cannot get harrdware acceleration to work:

Have you followed what is mentioned on this wiki page?

If so, what does /var/log/Xorg.0.log say?

Why are you using a vnc server? Do you want the X session to be remotely accessible?

[Adel Ahmed]

I have followed the page, for some reason I do not have a /var/log/Xorg.0.log
is there an alternate location or have I done something wrong?

Is this computer a laptop?

If so, are you sure you do not have 2 video cards? An integrated Intel video card for most display uses, and the Nvidia card for heavy display/graphics uses?

If you do have 2 video cards, you need to follow this: https://wiki.gentoo.org/wiki/NVIDIA/Optimus

I personally run X without systemd as suid root so X can write log files wherever it wishes. However the default now is to run X with or without systemd as the user. it is possible that X can't write to /var/log and instead I think it writes to the esoteric

Hello Adel Ahmed

did you tried killing you X session and:

[Ionen]

wrt minimal you don't want that, most of it is "fine" with nvidia except one thing, it does --disable-glx (so yeah...). Minimal is mostly intended for a headless machine wanting to run Xvfb or so.

Given your card, I assume you are using nvidia-drivers-390.xx branch, right?

When you built 390, did it complaint about enabling KMS_HELPER in the kernel? 390.xx needs a workaround to have working glx, but that workaround only gets activated (in xorg.conf.d's nvidia-390.conf) with DRM support using KMS_HELPER

Also, ensure you are in video group.

Will need to see Xorg's log if the above doesn't help.

Edit: also you shouldn't need to load modules yourself, nvidia-modprobe will automagic handle this + create devices with right permissions if you are in the video group as long as modules exist for your running kernel

yikes, it is a laptop, in this case I meant to run it using the discrete graphics card(intel)
I have change the use flags for the xorg-drivers as following:
Calculating dependencies... done!
[ebuild R ] x11-base/xorg-drivers-1.20-r2::gentoo INPUT_DEVICES="evdev -elographics -joystick -libinput -synaptics -vmmouse -void -wacom" VIDEO_CARDS="i915 intel -amdgpu -ast -dummy -fbdev (-freedreno) (-geode) -glint -i965 -mga -nouveau -nv -nvidia (-omap) -qxl -r128 -radeon -radeonsi -siliconmotion (-tegra) (-vc4) -vesa -via -virtualbox -vmware" 0 KiB


I get the same error

I removed the nvidia modules that I had installed earlier and now things work.

thanks everyone.
