Hello, i got the same problem as Sérgio Bessa. My enviroment is:
- Thinkpad x220 4290-w1b (Intel HD Graphics 3000), Ubuntu 11.04 x64 - external Monitor Samsung 2343BW @2048x1152, connected via VGA This problem arises, when my primary screen (notebook) is configured to be under my secondary screen (external Monitor). When my primary screen is left of my secondary screen everything works fine. For "lspci --vvnn" i think the following lines may be interesting: 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:21da] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 44 Region 0: Memory at d0000000 (64-bit, non-prefetchable) [size=4M] Region 2: Memory at c0000000 (64-bit, prefetchable) [size=256M] Region 4: I/O ports at 5000 [size=64] Expansion ROM at <unassigned> [disabled] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915 Hope that information may help.
