Bug#496747: xserver-xorg-video-ati: multi-head virtualsize and direct rendering not working with two different monitor resolutions

You can only correct this, if you open a console and type xrandr --output VGA-0 --auto. You have to do this every time you login. As I said, please send the whole ouput of xrandr --verbose before and after running the above xrandr --auto. I can't get the correct resolutions again. Also xrandr --output VGA-0 --auto doesn't work any more even though I used the old config. At the moment the picture from the big monitor (DVI) laps over on the small. It's like a small part of the desktop is cloned. xorg.conf: # xorg.conf (X.Org X Window System server configuration file) # # This file was generated by dexconf, the Debian X Configuration tool, using # values from the debconf database. # # Edit this file with caution, and see the xorg.conf manual page. # (Type man xorg.conf at the shell prompt.) # # This file is automatically updated on xserver-xorg package upgrades *only* # if it has not been modified since the last upgrade of the xserver-xorg # package. # # If you have edited this file but would like it to be automatically updated # again, run the following command: # sudo dpkg-reconfigure -phigh xserver-xorg Section InputDevice IdentifierGeneric Keyboard Driverkbd OptionXkbRulesxorg OptionXkbModelpc101 OptionXkbLayoutus EndSection Section InputDevice IdentifierConfigured Mouse Drivermouse OptionEmulate3Buttonstrue EndSection #Section Device #IdentifierConfigured Video Device #Driverfglrx #OptionMonitor-DVI-0 DVI Monitor #OptionMonitor-VGA-0 VGA Monitor #EndSection Section Monitor IdentifierDVI Monitor Modeline 1680x1050_60.00 147.14 1680 1784 1968 2256 1050 1051 1054 1087 -HSync +Vsync Option PreferredMode1680x1050_60.00 EndSection Section Monitor IdentifierVGA Monitor DisplaySize1280 1024 OptionRightOfDVI Monitor OptionDPMS EndSection Section Screen IdentifierDefault Screen #MonitorConfigured Monitor SubSection Display Depth 24 Virtual 4000 3000 EndSubSection EndSection xrandr --verbose before xrandr ... --auto: creen 0: minimum 320 x 200, current 2560 x 1024, maximum 3000 x 2000 VGA-0 connected 1280x1024+1280+0 (0x5f) normal (normal left inverted right x axis y axis) 338mm x 270mm Identifier: 0x5c Timestamp: 504510509 Subpixel: no subpixels Clones: DVI-0 S-video CRTC: 0 CRTCs: 0 1 EDID_DATA: 000009d145765603 1f0e01036c261e78ea5e0ca4594a9825 205054bdef80714f8180818c818f0101 010101010101302a009851002a403070 1300520e111e00fc0042656e 512046503939310a202000ff 0a20202000fd 00384c1e510e0a20202020202020004c load_detection: 1 (0x0001) range: (0,1) 1280x1024 (0x5f) 108.0MHz +HSync +VSync *current +preferred h: width 1280 start 1328 end 1440 total 1688 skew0 clock 64.0KHz v: height 1024 start 1025 end 1028 total 1066 clock 60.0Hz 1600x1024 (0x60) 106.9MHz -HSync -VSync h: width 1600 start 1620 end 1640 total 1670 skew0 clock 64.0KHz v: height 1024 start 1027 end 1030 total 1067 clock 60.0Hz 1400x1050 (0x61) 122.0MHz +HSync +VSync h: width 1400 start 1488 end 1640 total 1880 skew0 clock 64.9KHz v: height 1050 start 1052 end 1064 total 1082 clock 60.0Hz 1280x1024 (0x62) 138.8MHz -HSync +VSync h: width 1280 start 1368 end 1504 total 1728 skew0 clock 80.3KHz v: height 1024 start 1027 end 1034 total 1072 clock 74.9Hz 1280x1024 (0x63) 135.0MHz +HSync +VSync h: width 1280 start 1296 end 1440 total 1688 skew0 clock 80.0KHz v: height 1024 start 1025 end 1028 total 1066 clock 75.0Hz 1280x1024 (0x64) 133.0MHz -HSync +VSync h: width 1280 start 1368 end 1504 total 1728 skew0 clock 77.0KHz v: height 1024 start 1027 end 1034 total 1070 clock 71.9Hz 1280x1024 (0x65) 109.0MHz -HSync +VSync h: width 1280 start 1368 end 1496 total 1712 skew0 clock 63.7KHz v: height 1024 start 1027 end 1034 total 1063 clock 59.9Hz 1280x1024 (0x5f) 108.0MHz +HSync +VSync *current h: width 1280 start 1328 end 1440 total 1688 skew0 clock 64.0KHz v: height 1024 start 1025 end 1028 total 1066 clock 60.0Hz 1440x900 (0x66) 108.8MHz +HSync +VSync h: width 1440 start 1472 end 1880 total 1912 skew0 clock 56.9KHz v: height 900 start 918 end 927 total 946 clock 60.2Hz 1280x960 (0x67) 108.0MHz +HSync +VSync h: width 1280
Bug#496747: xserver-xorg-video-ati: multi-head virtualsize and direct rendering not working with two different monitor resolutions
Hello, since the original poster is a good friend of mine and I know his setup, I'd like to make some additions: The above Xorg.log-file was taken when he had 2 displays with the same resolution connected, but in fact the problem only appears when using two displays with different resolution: Setup 1: Display 1: 1280x1024, Benq, TFT, Connected with VGA Display 2: 1600x1080, DELL, TFT, COnnected with DVI Results: Direct Rendering does *not* work. glxinfo shows Direct Rendering: No. When starting X, the displays have, as already mentioned, have the same virtual display size (both using 1600x1080). Thus the 1280-display having the 1600-resolution, too. When checking the monitors display-menu though, the 1280-display is running at it's native 1280x1024. Calling xrandr --output VGA-0 --auto from an xterm immediately fixes that situation so both displays run with a virtual resolution matching their native hardware-resolution. Setup 2: Display 1: 1280x1024, Benq, TFT, Connected with VGA Display 2: 1280x1024, Samsung, TFT, Connected with DVI Results: Direct Rendering works, glxinfo shows Direct Rendering: Yes. Both displays have proper virtual resolution.

Also, you don't get debugging information from glxinfo. Please send the output of LIBGL_DEBUG=verbose glxinfo when if fails.
