Goal: To use two monitors for development.
specs - GIGABYTE G5 KF5 13620h i7, mesa intel graphics, and rtx 4060gb. using one hdmi port and other with usbc to hdmi.,
kde 22.04
when click on use xorg server no monitors are detected.
and this whole list becomes greyed out saying using custom software.
I have tried Optimus , it does not work ends as core dumped.
xrandr shows disconnected HDMI on xorg.
I have tried everything it only detects one monitor in nvidia and no monitors in xorg.
I am using kde for a while, but still naive in this situation , I have tried almost everything couldn’t find any resolution.
Any help is greatly appreciated
then reopen the driver manager. You should now see newer drivers. 535 is slightly broken and a bit old.
So far 550 works best with X11 but has issues with Wayland, and 555 works best with Wayland but has issues with X11. Choose which session type you want to use (with Nvidia its always recommended to use X11) and stick with it.
Switch to nouveau before updating drivers, and reboot. Give nouveau a little bit to sort itself out upon first boot. Then login, open an terminal and purge the old nvidia drivers before installing the new ones. Installing over existing drivers will often lead to problems:
sudo apt purge nvidia*
After its purged, then do
sudo apt clean
sudo apt autoremove
Then use the driver manager to install the new driver.
I missed the fact that the secondary monitor was running via USBC. I cannot help you with that. It seems you need a driver called displaylink. Perhaps try the steps in this:
sudo ./displaylink-driver-6.0.0-24.run

‘evdi’ Debian package appears to be installed.
This installer is incompatible with the packaged driver.
Yeah, just took a look at the displaylink website and its 10 years out of date. All the general websites I have found on the topic are ancient. LSB is long depreciated. Perhaps search for your specific device? Not sure how to help you other than suggest maybe posting in the Kubuntu forum to see if anybody there uses a USB display. I do not think the Plasma version would effect it that much, and the rest of Neon is pretty much standard Kubuntu 22.04.

The unit files have no installation config (WantedBy=, RequiredBy=, UpheldBy=,
Also=, or Alias= settings in the [Install] section, and DefaultInstance= for
template units). This means they are not meant to be enabled or disabled using systemctl.
Possible reasons for having these kinds of units are:
A unit may be statically enabled by being symlinked from another unit’s
.wants/, .requires/, or .upholds/ directory.
A unit’s purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, …).
In case of template units, the unit is meant to be enabled with some
instance name specified.

Please note that the evdi kernel module is still in the memory.
A reboot is required to fully complete the uninstallation process.

Did you follow the instructions and install it from the apt repo somebody posted?
Seems the .run does not work on ubuntu based systems. Follow the instructions to add the PPA and install it. Do not install the standalone.
I also recommend that you give Kubuntu a try, not Neon. As far as user experience goes, it is nearly identical, with the exception Kubuntu is a bit more compatible out of the box and a lot more polished. While Kubuntu wont be getting Plasma 6 until the end of October, there is actually no compelling need for P6 as its not really that different from P5.
