Thread: Graphics processor switched to llvmpipe?

    Question Graphics processor switched to llvmpipe?

    Hey guys, I just reinstalled the distro using the network installer and upon using it noticed that there are no animations on my kde DE, I can't change the screen brightness, and i experience a lot of screen tearing when scrolling on Firefox. I suspect it has something to do with the graphics processor using "llvmpipe" (I've never used it in my previous installations). Is there a way to switch it back to Mesa (I use integrated graphics).

    Is Mesa even installed? What does inxi -Gay report?

    Thanks for the response! I switched back to Fedora and I don't really want to switch back again, so I tried it on a virtual machine and the same issue was still there. I tried Inxi -Gay and got:
    Code:

    As I never use any OS except (PC) DOS in a virtual machine, I can't comment on inxi output from this on the basis of experience.

    I booted up a live environment using my flash drive and ran inxi -Gay again, which gave the following:

    Graphics:

    Device-1: Intel CoffeeLake-H GT2 [UHD Graphics 630] vendor: Hewlett-Packard
    driver: N/A alternate: i915 bus-ID: 00:02.0 chip-ID: 8086:3e9b
    class-ID: 0300
    Device-2: NVIDIA GP107M [GeForce GTX 1050 3 GB Max-Q]
    vendor: Hewlett-Packard driver: N/A alternate: nouveau bus-ID: 01:00.0
    chip-ID: 10de:1c91 class-ID: 0300
    Device-3: Chicony HP Wide Vision HD Camera type: USB driver: uvcvideo
    bus-ID: 1-5:3 chip-ID: 04f2:b627 class-ID: 0e02
    Display: x11 server: X.org 1.20.11 compositor: kwin_x11 driver:loaded: N/A
    note: n/a (using device driver) unloaded: fbdev,modesetting,vesa
    alternate: intel resolution: <missing: xdpyinfo>
    OpenGL:renderer: llvmpipe (LLVM 12.0.0 256 bits) v: 4.5 Mesa 21.0.2
    compat-v: 3.1 direct render: Yes

    Does this give any more information?

    Also, another thing I've noticed is that I have to use the kernel module "nomodeset" in order to access the installation and live environment or else only a blank screen appears.

    Using nomodeset blocks KMS. KMS is a foundation on which all competent X drivers depend. N/A suggests to me the inxi present on the running system used to present this is a broken antique version. Missing xdpyinfo is also unfortunate.

    The main thing this shows is you have dual graphics with Intel and NVidia GPUs. This is known as "Optimus", which requires special configuration. Start here and here.

    Try to disable Nvidia graphics in BIOS settings.

    There's isn't an option to disable Nvidia graphics from BIOS for my laptop.

    I tried installing the Nvidia drivers, but that didn't go well. After installing and rebooting no display would appear (even without the "nomodeset" kernel). I have installed the drivers successfully on openSUSE Tumbleweed a few months ago.

    It's quite strange why my device doesn't boot up without "nomodeset" now, even though I've installed this distro a couple of times without it.

    Alright, I think I've finally figured out why I can't boot without the "nomodeset" kernel parameter. It's probably due to the recent kernel which doesn't work on my laptop (The same issue occurred on Arch Linux with the latest kernel).

    Is there a way to install a previous version of the kernel on Tumbleweed?
