I'm working on a docked HP ProBook 650 and two external monitors.
On Windows it works fine, but my work requires me to use Linux (tried both Ubuntu and Debian).
Got two seperate problems:
- On Ubuntu all three monitors work - but my graphics twitch and break.
- On Debian only one monitor can be active others are in "disconnected" state
I've searched and tried a lot of things - but since I'm a novice in using Linux operating systems I'm seeking help on how to solve any of those two problems?
Or a suggestion for a better Linux option for a work station would be handy as well?
