Hi there,
I’ve been looking for a distro that could handle my particular setup and thought after a trial of various different distros that I’d found a solution in Fedora V42 with KDE.
Historically I’ve been a long time user of Debian however it seems to have a real problem working in reliable way with my setup such as not remembering resolutions, losing a monitor on restart/cold start or simply getting into a bind where I have to reset the display configuration, which is why I ended up trying out Fedora.
My setup is as follows;
- HP ProBook 450 G6 with 32GB RAM and 500GB NVME drive
- MST is enabled in the BIOS and this works fine under Windows 11 with both displays running at 60Hz
- HP USB-C Dock G5
- Firmware on the Dock is latest available version
- 2 x Dell U3219Q 4K monitors (both have a 60Hz max refresh rate)
- Both displays are connected via DisplayPort cables from the Dock
- Both displays have the same firmware version
- As far as I’m aware they should be on the same DisplayPort version
After some tweaking with the display setup in KDE, I’ve got to a point where I can run both my 4K monitors at native resolution (albeit at 30Hz) which isn’t ideal, but I can work with.
The same setup in Windows 11 though and both monitors will run at 60Hz which is puzzling.
My only issue with this setup right now is that if I do a Complete shutdown of the laptop, the next time I boot it up while it’s connected to the HP Dock, it defaults to the internal display panel only. It doesn’t seem to initialise the two external displays as neither power up at this stage.
The only workaround I have right now is to open up the laptop, enter my password on the login screen and wait for KDE to initialise. Then I can close the laptop (which puts it into sleep mode), place the laptop back into the vertical desktop holder and then wake up the laptop via the button on the HP Dock.
Once the laptop has properly woken up, both external displays power on and initialise at 4K then I can unlock the laptop and carry on with my day.
Does anyone have any recommendations for how I might setup Fedora and/or KDE to initialise the external displays automatically when my laptop is docked instead of it defaulting to the internal laptop display?
Thanks in advance!
