Hi, I have an issue with dual monitors with a 9070 GPU
OS: OpenMandriva Lx 25.04 (ROME) Rolling x86_64
Kernel: Linux 6.14.0-desktop-3omv2590
DE: KDE Plasma 6.3.3
WM: KWin (Wayland)
AMD Driver: AMDVLK2025.Q1.3
This issue DID NOT happen on my previous GPU a 7900XTX and it also didn’t happen on the RX 6600 I also had installed at one point.
Screen configuration:
1x 3440x1440 widescreen as primary
1x 3840x2160 as secondary
Every time I launch a game it keeps trying to launch on the secondary screen when the widescreen one is set to PRIMARY.
they both are plugged into the display ports, secondary one is plugged in with a DP to HDMI adapter and the primary widescreen one is plugged in directly to DP.
I tried connecting the secondary screen to HDMI and things got worse, the primary widescreen monitor keep flickering and glitching out.
to temporarily fix the problem I connect them both to DP and then try to launch a game if it launches on the wrong screen I disable the secondary one and run the game, then close the game and re-enable second screen and then the game runs on the primary one, it’s quite frustrating.
It happens on both MESA and AMDVLK2025.Q1.3 drivers.
It’s even IGNORING the in game monitor choice, if I pick primary as the widescreen in the game, it’s still using the other monitor, it’s driving me nuts.
Is there any way to force games to run on the primary screen? (I am not sure if this is even a KDE issue, I asked this same question on the OpenMandriva forum also.)
Also one last note, the secondary monitor DOES have the ability to connect directly to DP, the problem is I use a capture card with that screen and the capture card is only HDMI, just connecting the screen directly to HDMI is causing weird problems like I mentioned above.
