Hi,
I had a similar problem with my system. I solved it by forcing xrandr to
use a higher resolution. I'm not sure, if this is a good way, but it works
quite good for me.
1. Open a Terminal and type in "cvt screen_resolution":
$ cvt 1680 1050 60
You will get something like this (your's could be slightly other output):
# 1680x1050 59.95 Hz (CVT 1.76MA) hsync: 65.29 kHz; pclk: 146.25 MHz
Modeline "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync
2. Create new xrandr mode with information from above:
$ xrandr --newmode "stuff after >Modeline< above"
So in my case:
$ xrandr --newmode "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050
1053 1059 1089 -hsync +vsync
3. Check the name of the output device. You get it from
$ xrandr --query
E.g.:
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 16384 x 16384
LVDS-1 connected
1366x768 59.99 +
1360x768 59.80 59.96
...
VGA-1 disconnected
HDMI-1 connected primary 1920x1080+0+0 477mm x 268mm
1920x1080 60.00*+
...
4. Adding this mode to the output device you are using. In my case it was
VGA-1.
$ xrandr --addmode VGA-1 "1680x1050_60.00"
5. Setting new mode:
$ xrandr --output VGA-1 --mode "1680x1050_60.00"
If you do this one time, you can put 2.+4.+5. in a shell script and execute
it by startup or something. I wrote my script to be a switch between laptop
screen and external monitor, because it didn't worked another way. Until
now it is fixed on my machine.
I hope, this is useful.
Best regards,
Stefan

Lubuntu Users:
One of my machines, running Lubuntu 16.04, has a monitor which has been
working (as long as we can remember on 14.04, and a long time after
upgrading to 16.04) at a resolution of 1680 x 1050 (or something like
that). And it still runs with that resolution on Windows 10. ...
Hi Aere,
This is too bad. I suspect that a bad version of the graphics
driver came with an updated kernel. It might work better, if you
[re-install and] use an older version of the linux kernel.
Please tell us about the graphics chip/card, and which graphics
driver, that is used now!
Best regards
Nio
