Toggle/switch to the nv card $ cat /sys/kernel/debug/vgaswitcheroo/switch $ echo "0000:01:00.0" /sys/kernel/debug/vgaswitcheroo/switch 2. Confirm that the nv card is used (paste the output in your reply) $ cat /sys/kernel/debug/vgaswitcheroo/switch 3. Start X $ init 5 #startx # systemd start {g,k,x}dm and then attach the output of the following (plain text, please) * dmesg * Xorg.0.log * LIBGL_DEBUG=verbose glxinfo * LIBGL_DEBUG=verbose DRI_PRIME=1 glxinfo Thanks</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
