On T500 thinkpad, I enabled KMS on i915, and noticed that only a single mode shows up in xrandr output. Without kms, all modes are supported. Tested on 2.6.30 and 2.6.29.4-167 that ships with Fedora.
xrandr output: With kms enabled: Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192 VGA1 disconnected (normal left inverted right x axis y axis) LVDS1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 331mm x 207mm 1680x1050 60.1*+ 50.1 DVI1 disconnected (normal left inverted right x axis y axis) DVI2 disconnected (normal left inverted right x axis y axis) Without kms enabled: Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 1680 x 1680 VGA disconnected (normal left inverted right x axis y axis) LVDS connected 1280x1024+0+0 (normal left inverted right x axis y axis) 331mm x 207mm 1680x1050 60.1 + 50.1 1400x1050 74.8 60.0 1280x1024 85.0 75.0 60.0* 1280x960 85.0 60.0 1152x864 75.0 1024x768 85.0 75.0 70.1 60.0 832x624 74.6 800x600 85.1 72.2 75.0 60.3 56.2 640x480 85.0 72.8 75.0 59.9 720x400 85.0 640x400 85.1 640x350 85.1 HDMI-1 disconnected (normal left inverted right x axis y axis) HDMI-2 disconnected (normal left inverted right x axis y axis) hardware: $ sudo lspci -vv -s 00:02.0 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device 20e4 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 28 Region 0: Memory at f4400000 (64-bit, non-prefetchable) [size=4M] Region 2: Memory at d0000000 (64-bit, prefetchable) [size=256M] Region 4: I/O ports at 1800 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Mask- 64bit- Count=1/1 Enable+ Address: fee0100c Data: 4189 Capabilities: [d0] Power Management version 3 Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Kernel driver in use: i915 -- MST ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
