about two weeks ago I asked for some help with getting my Egpu setup working with my Thinkpad T480 internal screen and it worked as expected. since then I bought myself an external monitor since I’ve been told that how you get the best performance with it. doing that though has brought in some unique issues starting with the bizarre slowdown on the external monitor when I set it as a single display in gnome settings or close my laptop screen. If I try to play games on Steam, I actually get worse performance on the external monitor than I did on the internal monitor! Both Fallout New Vegas and Team Fortress 2 went from 60 fps to 40 fps on the exact same setting’s (i.e the one I used when playing the games using only the laptop screen) and also seem to be hard wired to whatever resolution my internal laptop screen is (trying to change it in team fortress 2 seems to cause it to lock up). I’m really confused what’s going here cause when I run the command DRI_PRIME=1 glxinfo | grep “OpenGL renderer” it does show my rx 580 being used which should means it’s working. So what should be my next step to trouble shoot this?
Please post the output of inxi -Fazy and xrandr --listproviders.
hmmmm all I get is Error 22: Unsupported option: and
Check -h for correct parameters.
okay I switched and to && and this is what outputted

I believe this is caused by limitations in the Xorg server, the issue is the same as described here.
Have you tried using Wayland? And what’s the output of sudo cat /sys/kernel/debug/vgaswitcheroo/switch?
switch to wayland then run that command?
Run that command in the X session, so no need to switch to anything.
if I run the command I get the error zsh: no matches found: ? and if I remove the ? it just tells me that cat: /sys/kernel/debug/vgaswitcheroo/switch: No such file or directory
I see. I’m not quite sure if this will achieve anything meaningful, but what happens if you run
xrandr --setprovideroutputsource "Radeon RX 580 Series @ pci:0000:09:00.0" 0x0
xrandr --setprovideroutputsource Intel "Radeon RX 580 Series @ pci:0000:09:00.0"
?
If you get a black screen on both displays, just press Ctrl+Alt+F3, and log in, then reboot.
well running the first one froze my external monitor but it showed xrandr --setprovideroutputsource “Radeon RX 580 Series @ pci:0000:09:00.0” 0x0 let’s see what happens when I run the second one
That was expected.
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 35 (RRSetProviderOutputSource)
Value in failed request: 0xb6
Serial number of failed request: 16
Current serial number in output stream: 17
I see. Running xrandr --setprovideroutputsource "Radeon RX 580 Series @ pci:0000:09:00.0" Intel should restore the external monitor. In any case, I suggest you try Wayland.
Interesting. Most of my research made it seem like epgu wouldnt work with wayland
I guess it’s worth a try.
wayland definetly fixed my monitor issue I’ll see what happens now when I run a few games
sorry this took forever but after trying a few games which were still playing very choppily I decided to try shadow of the tomb raider which interestingly enough recognized the amd card but still played super choppy at 30 fps on low and high settings. so now I’m really confused what could be causing this
What’s the output of
glxinfo -B | grep renderer
DRI_PRIME=1 glxinfo -B | grep renderer
?
Extended renderer info (GLX_MESA_query_renderer):
OpenGL renderer string: Mesa Intel® UHD Graphics 620 (KBL GT2)
Extended renderer info (GLX_MESA_query_renderer):
OpenGL renderer string: Radeon RX 580 Series (POLARIS10, DRM 3.40.0, 5.10.2-2-MANJARO, LLVM 11.0.0)
Are you back on X11? You ran the games with DRI_PRIME=1 right?
