Tested On: Ubuntu Gnome 16.04 LTS
I had an issues with getting my HiDPI display, 3200x1800, working correctly with Chromium. By default, Chromium supports high resolutions but does not adapt manually.
So, I found a work-around to get it to work and wanted to share it with everyone else.
Originally searched:
$ cd / && find -iname 'chromium*'
Returned a lot of results... If your results where anything like mine, you will see a file in: /etc/chromium-browser/default
Edit this file (all preference):
$ sudo nano /etc/chromium-browser/default
There is a section that has a variable for arguments to pass to the actual file being called in the /bin folder.
It looks like:
CHROMIUM_FLAGS=””
CHANGE it to:
CHROMIUM_FLAGS=”--force-device-scale-factor=2”
Save the changes and restart Chromium. That should fix Chromium for those that want to use Chromium with a higher resolution.
[NOTICE] Please keep in mind, the scaling factor takes a floating point value, so you can scale to something like 1.25 or 2.13, or whatever preference you want.
Hope this helps.
