Hi folks,
Super happy x2go user on a Thinkpad P1 Gen2 with a 4k screen running Fedora with XFCE. I segregate clients and personal work into distinct users and run 5 or 6 x2go sessions at the same time, switching between them with desktop workspace hotkeys monitored by the master session. Performance is great, even video within an x2go session is terrific.
Today the Thinkpad's screen decided to start to fail, so I connected the laptop over HDMI to a 4k external monitor. Now, unfortunately, x2go performance is really suffering- window repaints within a session even with only 1 session are so slow as to be essentially unusable. Window repaints and other rendering activity on the master X session seem about the same.
All sessions are 3840x2160, using "LAN", "16m-jpeg", image quality 9. I played a little with those settings but nothing made a material difference. I don't know anything about the X display architecture or the hardware path. Any thoughts from anyone who does on any options to improve x2go performance on an external monitor?
Thanks, cheers,
Jonah
Resolved! For future reference: I disable Compositing in the x2go sessions because it makes XFCE unusable. I had ALSO disabled Compositing in the master session. Re-enabling it in the master resolved the performance issues in the x2go sessions on the external monitor. Who knew?
Cheers,
Jonah
