Public bug reported: Binary package hint: xrandr
I have a shuttle xpc with a on board ATI Technologies Inc RS480 [Radeon Xpress 200G Series] the xpc was a VGA output that I have connected to a DELL 24'' wide screen 1920x1200 and a DVI port that I have connect to HDMI HDTV with 1080i support. If I have the VGA cable plugged to the xpc, the xrandr resolution detection works as expected. But if I plug the DVI cable to the xpc box, to have dual screen, xrandr does not detect a new monitor. And if I start the xserver again I get the resolution of the HD TV I get image on both screens, but only the HDTV is displaying with a good resolution. I'm using ATI drivers. If I use the open version for ati chipsets and I plug the VGA and DVI cable I get no image on both screens. If I plug the VGA I get a strange resolution if I use the VGA cable, I did not try using just the DVI cable with the OSS driver. I someone knows a work around about using a onboard ati card with dualhead configuration, with the latest ubuntu gutsy, please drop me a email. Feisty was even worse, both using the OSS and same ati drivers. I was never able to have the DELL screen at 1920x1200 and the HDTV and 1920x1080 with bigscreen. only VGA cable is plugged: [EMAIL PROTECTED]:/proc$ xrandr Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 1920 x 1200 default connected 1920x1200+0+0 0mm x 0mm 1920x1200 60.0* 1600x1200 60.0 1280x1024 75.0 70.0 60.0 1152x864 75.0 70.0 60.0 1024x768 75.0 72.0 70.0 60.0 1024x480 60.0 848x480 60.0 800x600 75.0 72.0 70.0 60.0 56.0 47.0 720x576 60.0 720x480 60.0 640x480 75.0 72.0 60.0 640x400 75.0 60.0 512x384 60.0 400x300 75.0 60.0 320x240 75.0 60.0 320x200 75.0 60.0 Both VGA and DVI after X is restarted: [EMAIL PROTECTED]:~$ xrandr Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 1920 x 1080 default connected 1920x1080+0+0 0mm x 0mm 1920x1080 30.0* 1776x1000 30.0 1280x1024 75.0 70.0 60.0 1152x864 75.0 70.0 60.0 1280x720 60.0 1024x768 75.0 72.0 70.0 60.0 1152x648 60.0 1024x480 60.0 848x480 60.0 800x600 75.0 72.0 70.0 60.0 56.0 47.0 720x576 60.0 720x480 60.0 30.0 640x480 75.0 72.0 60.0 640x400 75.0 60.0 512x384 60.0 400x300 75.0 60.0 320x240 75.0 60.0 320x200 75.0 60.0 [EMAIL PROTECTED]:/proc$ fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc.
