I use a Pentium IV PC [Hewlett-Packard HP D530 CMT(DC577AV)] containing the 'Intel Corporation 82865G Integrated Graphics Controller' with an HD TV set as a monitor. I have to use the integrated graphics because I was not able to install Ubuntu with an external graphics card and found no linux driver for the external card. Therefore I have to use a VGA connection.
Under Windows XP the resolution 1920x1080, 60 Hz, works precisely this way. 'Ubuntu 12.04.2 LTS' enables precisely the same resolution and frequency with a monitor that it recognizes, even using VGA connection. But the Ubuntu does not recognize my TV set and, with the TVset, it does not offer the 1920x1080 resolution.
According to https://askubuntu.com/questions/298797/intel-driver-cannot-detect-my-monitor-and-get-native-resolution?rq=1 and http://www.garrypassarella.co.uk/2011/04/23/add-undetected-resolutions-in-ubuntu/ I have got the resolution 1920x1080, 60 Hz for a moment using Terminal
$ xrandr Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2048 x 2048 VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 $ cvt 1920 1080 60 1920x1080 59.96 Hz (CVT) hsync: 79.57 kHz; pclk: 206.25 MHz Modeline "1920x1080_60.00" 206.25 1920 2056 2256 2592 1080 1283 1293 1327 -hsync +vsync $ xrandr -newmode "1920x1080_60.00" 206.25 1920 2056 2256 2592 1080 1283 1293 1327 -hsync +vsync and $ xrandr --addmode VGA1 "1920x1080_60.00" .
I need to continue adding the resolution into the Ubuntu displays menu because, in a new run, the Ubuntu 'System Settings'...'Displays' offers only the former '1024x768 (4:3)' and '800x600 (4:3)' resolutions.
According to the http://www.garrypassarella.co.uk/2011/04/23/add-undetected-resolutions-in-ubuntu/ :
I see no
/etc/X11/xorg.conf file in that directory. I have tried
gsudo service gdm stop with a result
gdm: unrecognized service . I have tried
Xorg -configure with a result
Fatal server error: Server is already active for display 0
I am new with Ubuntu. Please advise me, how to add the new resolution into the Ubuntu displays menu, thanks,
