To list the drivers I do this (please note the "name:" entry): xrandr --listproviders Providers: number : 2 Provider 0: id: 0x6f cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 3 associated providers: 1 name:modesetting Provider 1: id: 0x49 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 6 outputs: 4 associated providers: 1 name:PITCAIRN @ pci:0000:01:00.0 If I'd see no modesetting info from the previous output I'd check config files in /etc/modprobe.d/ or /etc/default/grub (or wherever) that switch off modesetting I didn't find recent docs for Fedora re. this, but here's some info from Debian pages: -------------------- To disable KMS for Intel and Radeon cards, either: Boot with the nomodeset kernel command line parameter. Edit /etc/modprobe.d/i915-kms.conf or /etc/modprobe.d/radeon-kms.conf accordingly. To disable KMS for nVidia cards, either: Boot with the nomodeset kernel command line parameter. Blacklist the nouveau kernel module, e.g. with echo blacklist nouveau > /etc/modprobe.d/blacklist-nouveau.conf and create a minimal /etc/X11/xorg.conf specifying the desired driver, e.g. [ ... ] Setting via Grub Configuring the KMS via Grub can be done via the /etc/default/grub config file by doing something similar to the following: [ .... ] -------------- The rest at: https://wiki.debian.org/KernelModesetting Again: some look to /etc/modprobe.d/ etc. might be useful This might be useful, too: https://wiki.debian.org/AtiHowTo HTH, Wolfgang _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
