    If you launch mullvad from the app icon, try you add to PrefersNonDefaultGPU=true (or false) in mullvad-vpn.desktop (cp /usr/share/applications/mullvad-vpn.desktop ~/.local/share/applications

    If it is autostarted add it in .config/autostart/mullvad-vpn.desktop

    Or add --disable-gpu to the in Exec : Exec="/opt/Mullvad VPN/mullvad-vpn" --disable-gpu %U



  • Hello OP, on this kind of system GNOME should use the igpu by default and the dGPU only when an App “launched with dedicated graphics” from the menu, or with DRI_PRIME=1 from the command line. (Also some vulkan game can also select the dgpu)

    If that is not the case this is a bug.

    Are you using x11 or wayland, can you see what is using the dgpu with nvtop ?

    I got a gen 3, basically what is not working are :

    • Internal MIcrophone
    • Back Camera
    • Fingerprint reader
    • FnLock key Everything else is working well enough so far for me. S2idle is working way more reliably on this device than on my SP4 but with a bit a tinkering I think that you can get S3 sleep working.

  • SP4 owner here, you should avoid the pro 4, one of its revision (with the samsung display) is very prone to touch screen defects, see this issue.

    I’m avoiding surface in general now, after using linux-surface for a year, I finally gave up and got myself a thinkpad x1 tablet. Even without the touchscreen issues, my experience with my SP4 was never good, the cameras needs libcamera and are awful, audio input randomly stopped working after sleep,I had blackscreen issues after login, and random freeze.

    Former gentoo user here. Compiling everything yourself does not magically improve performance. You have to use keep track of USEFLAGS, ideally cherry picking for some package because some can cause bugs or performance regressions.

    It can be really time consuming both compiling gentoo and trying different configurations. (But you’ll learn a lot of compilation/ build system knowledge along the way)

    My advise is that if you have time and want to experiment and learn, sure go with gentoo. If not and performance is absolutely critical then go with Clear Linux, otherwise take your popular distro of choice, package availability and ease of use are more important than a couple of % in performance improvement IMHO.


  • By default audio is often configured to run properly on the crappiest sound card and CPU. Since you used easyeffect I assume you use pipeWire. Here some of my config : In pipewire.conf :

    default.clock.rate          = 96000
     default.clock.allowed-rates = [ 44100 48000 96000 192000 ]
    

    In pipewire-pulse.conf

    stream.properties = {
        resample.quality      = 10
    }
    




  • I really love gentoo, by being sourced-based it really offers a lot of customization and flexibility compared to other distros. Software availability is usually not a problem, there is a lot of overlays and in worst case scenario writing an ebuild is not that difficult. Unfortunately the compile time on my machine makes it unusable for myself.

    In second Arch or Artix-s6, wether I need/want systemd or not. What makes arch good is clearly the huge collection of ports available on the AUR and the quality of the arch wiki (wich can work on other distros btw. If a package isn’t on the AUR, writing PKGBUILD isn’t very difficult. In the case of artix, the s6 supervision suite is a very good piece of software.

    And finally on low spec hardware, I really like alpine Linux, it’s running very well on my VPS on wich I host some services. Alpine Wall is great for firewall configuration .Software availability is a bit more weak due to Musl, but I foud what I needed, also APKBUILD is very similar to PKGBUILD. Honnestly it’s been very stable in this server use-case, and l’m happy with it.
