I hooked up a screen with a HDMI->DVI cable but the screen doesn't show a picture. The notebook displays an image on the external DVI screen in Windows 7. To me it seems that at least some communication from the screen to the graphics card works. But no image signal is sent from the graphics card to the screen. Regards, Martin And here is some more information: martin@hop:~$ uname -a Linux hop 2.6.37-rc3 #1 SMP PREEMPT Fri Nov 26 08:16:21 GMT 2010 x86_64 GNU/Linux martin@hop:~$ sudo lspci -v -s 01:05.0 [sudo] password for martin: 01:05.0 VGA compatible controller: ATI Technologies Inc M880G [Mobility Radeon HD 4200] (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 142c Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at c0000000 (32-bit, prefetchable) [size=256M] I/O ports at 5000 [size=256] Memory at d4300000 (32-bit, non-prefetchable) [size=64K] Memory at d4200000 (32-bit, non-prefetchable) [size=1M] Expansion ROM at <unassigned> [disabled] Capabilities: [50] Power Management version 3 Capabilities: [a0] MSI: Enable- Count=1/1 Maskable- 64bit+ martin@hop:~$ xrandr --output HDMI-0 --mode 1280x1024; xrandr Screen 0: minimum 320 x 200, current 1366 x 1024, maximum 1366 x 1366 VGA-0 disconnected (normal left inverted right x axis y axis) LVDS connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm 1366x768 60.0*+ 1280x720 59.9 1152x768 59.8 1024x768 59.9 800x600 59.9 640x480 59.4 HDMI-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 338mm x 270mm 1280x1024 60.0*+ 1280x960 60.0 1152x864 75.0 1024x768 75.0 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 75.0 72.8 66.7 59.9 720x400 70.1 some parts of /var/log/Xorg.0.log that seem interesting: [...] (--) PCI:*(0:1:5:0) 1002:9712:103c:142c ATI Technologies Inc M880G [Mobility Radeon HD 4200] rev 0, Mem @ 0xc0000000/268435456, 0xd4300000/65536, 0xd4200000/1048576, I/O @ 0x00005000/256 [...] (II) LoadModule: "radeon" (II) Loading /usr/lib/xorg/modules/drivers/radeon_drv.so (II) Module radeon: vendor="X.Org Foundation" compiled for 1.7.7, module version = 6.14.99 Module class: X.Org Video Driver ABI class: X.Org Video Driver, version 6.0 [...] (II) RADEON(0): PLL parameters: rf=10000 rd=12 min=90000 max=120000; xclk=40000 (WW) RADEON(0): LVDS Info: XRes: 1366, YRes: 768, DotClock: 69300 HBlank: 114, HOverPlus: 48, HSyncWidth: 32 VBlank: 12, VOverPlus: 2, VSyncWidth: 5 (II) RADEON(0): Output VGA-0 using monitor section aticonfig-Monitor[0]-0 (II) RADEON(0): I2C bus "VGA-0" initialized.
