I thought to provide the output of the same command run on Cauldron M9:

As that's a hybrid graphics system, probably best to try it with Mageia prime and the proprietary nvidia module to see if that fixes the issue. https://wiki.mageia.org/en/Mageia-prime_for_Optimus CC:

davidwhodgins Even if it does, we have something that works for M8 but not M9; and should know why. This might be change to document for M9. CC:

lewyssmith It's most likely a change in the i915 kernel module. There may be some new kernel option to avoid the issue. Assigning to kernel and drivers Assignee:

(none) I have changed the refresh rate in systemsettings for this monitor from 60Hz to 50Hz, where it seems to be good and stable now. Weird though, since it works fine with 60Hz on M8!! For me this can be set as resolved unless further actions are advised by the assignees :) |
Testing Cauldron on my Asus ROG laptop after the latest updates to date, I can no more use my external monitor connected through HDMI to the laptop. The Plasma desktop flickers annoyingly and the fonts get blurred and unclear. I can boot on my M8 installation on the same laptop, where everything works just fine. Here's a summary of my graphics from M8: $ inxi -Ga Graphics: Device-1: Intel HD Graphics 530 vendor: ASUSTeK driver: i915 v: kernel bus ID: 00:02.0 chip ID: 8086:191b Device-2: NVIDIA GM107M [GeForce GTX 960M] vendor: ASUSTeK driver: nouveau v: kernel alternate: nvidiafb,nvidia_drm,nvidia_current bus ID: 01:00.0 chip ID: 10de:139b Device-3: Chicony USB2.0 HD UVC WebCam type: USB driver: uvcvideo bus ID: 1-4:3 chip ID: 04f2:b424 serial: 0x0001 Display: x11 server: Mageia X.org 1.20.14 compositor: kwin_x11 driver: intel alternate: nvidia display ID: :0 screens: 1 Screen-1: 0 s-res: 3840x1080 s-dpi: 96 s-size: 1013x285mm (39.9x11.2") s-diag: 1052mm (41.4") Monitor-1: eDP1 res: 1920x1080 hz: 60 dpi: 143 size: 340x190mm (13.4x7.5") diag: 389mm (15.3") Monitor-2: HDMI2 res: 1920x1080 hz: 60 dpi: 92 size: 530x300mm (20.9x11.8") diag: 609mm (24") OpenGL: renderer: Mesa Intel HD Graphics 530 (SKL GT2) v: 4.6 Mesa 21.3.2 direct render: Yes
