Public bug reported: Binary package hint: xserver-xorg
Hi, this is rather a wish than a bug report. I connected an ubuntu machine with an HDMI cable to a small LCD TV. Unfortunately, the TV's firmware is not that good. Although the TV has a 1366x768 panel, it only lists 1920x1080 and 720x480 as possible resolutions. The X11 server refuses to use any other than those two listed resolutions, even if configured in xorg.conf. (The manufacturer says, it is not possible to use the TV with any other resolution, not even in the panel's resolution of 1366x768.) Unfortunately it is impossible to get an acceptable resolution, because 1920x1080 is scaled down and blurred, while 720x480 is scaled up and again, blurred. But then something curios happened: Accicendtly I pulled a little bit at the HDMI cable and it slipped out of the plug just a little bit. Then, the BIOS and Linux in console mode did not show anything on the TV anymore and instead used the analog VGA port. But once the X11 server started, it chose the resolution of 1366x768 as configured in xorg.conf, and even the TV accepted it, displaying 1360x768 as resolution (don't ask me why it detected 1360 instead of 1366), and the display was absolutely sharp and perfect, and in the correct resolution. So I guess that the losen HDMI cable allowed to transmit the signal from the PC to the TV, but not from the TV to the PC. PC could not detect the TV and read its table. This shows that it would be usefull to have an option to force the X11 server to ignore the resolution table reported by the screen on DVI and HDMI and to rigorosly use the given resolution as an override, in order to circumvent firmware problems as described. regards ** Affects: xorg (Ubuntu) Importance: Undecided Status: New -- Need to override HDMI resolution list https://bugs.launchpad.net/bugs/409018 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
