I just have this strange behavior and couldn't find out what is wrong. Anyone ever saw this kind of error? I checked the xorg log, but wasn't able to identify any obvious error.
- Notebook as first monitor (1366x768)
- Samsung P2370 as secondary monitor (1920x1080)
- Dell Inspiron 15R
- Ubuntu 12.04 fully updated
- ATI proprietary drivers
lspci relevant output:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Seymour [Radeon HD 6400M Series]
OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: AMD Radeon HD 7400M Series OpenGL version string: 4.2.12172 Compatibility Profile Context 12.10.17
I can attach xorg conf/log, if someone points me the relevant sections.
Thanks for any help.
