I was able to fix the problem with a workaround: - I know from the TV specifications (and from Lucid settings) that the maximum resolution of one of my Panasonic TV is 1360x756 - I search for the 1360x768 modeline: cvt 1360 768 - I obtain a modeline, wich I add to the TV (VGA1) with xrandr: xrandr --newmode "1360x768_60.00" 84.75 1360 1432 1568 1776 768 771 781 798 -hsync +vsync xrandr --addmode VGA1 1360x768_60.00
Then, I write a script where I add the modeline, switch off everything, than switch on both the TV and the notebook screen (LVDS1). In my case I place the TV on top, because my Intel graphic board doesn't allow a horizontal resolution larger than 4096. Here's teh script: #1/bin/bash xrandr --newmode "1360x768_60.00" 84.75 1360 1432 1568 1776 768 771 781 798 -hsync +vsync xrandr --addmode VGA1 1360x768_60.00 xrandr --output VGA1 --off xrandr --output LVDS1 --off xrandr --output VGA1 --mode 1360x768_60.00 --pos 0x0 --output LVDS1 --mode 1024x600 --pos 0x768 When I launch this script I have a correct resolution on both my screens. Obvioulsy, I make a different script for the other Panasonic TV too (which has a different maximum resolution). Tested only with an Intel graphic card. With Nvidia Nuveau I didn't try (I'm still using the proprietary driver and it seems to work, with some workaraounds too). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/973163 Title: Xorg doesn't detect correct resolution of VGA Panasonic TV To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/973163/+subscriptions _______________________________________________ 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
