It appears Xorg (or the kernel) can't detect the EDID of your monitor via the VGA connection:
[ 55.901] (II) modeset(0): EDID for output VGA-1 [ 55.901] (II) modeset(0): Printing probed modes for output VGA-1 [ 55.901] (II) modeset(0): Modeline "1024x768"x60.0 65.00 1024 1048 1184 1344 768 771 777 806 -hsync -vsync (48.4 kHz e) [ 55.901] (II) modeset(0): Modeline "800x600"x60.3 40.00 800 840 968 1056 600 601 605 628 +hsync +vsync (37.9 kHz e) [ 55.901] (II) modeset(0): Modeline "800x600"x56.2 36.00 800 824 896 1024 600 601 603 625 +hsync +vsync (35.2 kHz e) [ 55.901] (II) modeset(0): Modeline "848x480"x60.0 33.75 848 864 976 1088 480 486 494 517 +hsync +vsync (31.0 kHz e) [ 55.901] (II) modeset(0): Modeline "640x480"x59.9 25.18 640 656 752 800 480 490 492 525 -hsync -vsync (31.5 kHz e) So only standard modes are provided in order to avoid guessing and damaging the monitor. In order to allow the system to detect your monitor properly, please use the DVI port instead. If you can't do that then try a different VGA cable. But a monitor connected via your digital port (DVI) would be best. P.S. You also seem to be using the 'oibaf' PPA which is not supported by Ubuntu. ** Changed in: xorg (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1833855 Title: video card Status in xorg package in Ubuntu: Invalid Bug description: hi! some problem. i have an video intel graphic card Q965 but i dont have any hi-resolution like 1080. i'm in vga mode only.
