I recently installed Ubuntu 13.04 on my Acer Aspire TimelineX 5820TG laptop. I'm having a couple of issues with the graphics though:
- When I boot into Ubuntu from Grub with an external monitor attached, Ubuntu will always start in low graphics mode. (Disconnecting the external monitor before booting will allow it boot normally)
- When I resume from suspend with an external monitor attached, Ubuntu freezes (can't do anything)
- In the "Display" section of "System Settings", Ubuntu detects two laptop monitors and an "Unknown" display in addition to my external monitor. The two laptop monitors may have something to do with having hybrid graphics, but I have no idea what the "Unknown" one could be
- My laptop uses hybrid Intel/ATI graphics, and I'm currently using vgaswitcheroo as a work around (to solve overheating issues). However, after turning off the discrete graphics card, Ubuntu never shuts down immediately, but instead, says something about being stuck in an atombios loop
My main issue would be the problems with the external monitor. I've tried following guides on how to install Catalyst Control Center and proprietary ATI drivers in Ubuntu 13.04 to see if it would resolve the issue. However, when I attempt these solutions, I always end up in low graphics mode and have to reinstall Ubuntu. Currently vgaswitcheroo seems to be a good enough workaround (the atombios issue is just annoying).
I should also note that I'm using a VGA cable to connect to my monitor, not an HDMI one. I believe that the HDMI connection only works if my discrete graphics card is turned on.
