I’ve got new computer, connected on board VGA to the old monitor with 1900x1080 resolution, installed 13.1, run the updates, but now it tells me that the highest supported resolution is 1600x1050.
Mainboard manual says that on board “D-sub” port supports up to 1920x1200
linux-pwfe:/home/stan # /sbin/lspci -nnk | grep VGA -A2
00:02.0 VGA compatible controller : Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)
Subsystem: Gigabyte Technology Co., Ltd Device [1458:d000]
Kernel driver in use: i915
If it helps, Kinfocenter under OpenGL shows Renderer as “Mesa DRI Intel(R) Haswell Desktop” with OpenGL version “3.0 Mesa 9.2.3”
What should I do about it?
Could you please post the file /var/log/Xorg.0.log?
Apparently the monitor’s resolution is not detected correctly.
Is it connected directly or via some KVM switch?
Try to unplug it completely (also the power connection), and then connect it again.
Might help with EDID issues.
Unplugging (even from mains) didn’t help.after restart it’s still the same.
Xorg log is here
Well, the monitor apparently tells the driver that it’s highest recommended/supported resolution is 1680x1050.
What kind of monitor is this?
Are you sure it’s resolution is higher than 1680x1050? (it doesn’t matter what the plug on your mainboard supports)
If you want to use a higher resolution (will look blurry on modern LCD monitors), you would have to create an additional modeline to the X configuration.
See here for how to do that:
Indeed, it only looks big enough for HD but max supported resolution is only 1680x1050.
I am such a fool, should have googled native resolution first.
