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 1920×1080, 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 1920×1080 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 1920×1080, 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 '1024×768 (4:3)' and '800×600 (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,
