Text and windows too small on high resolution screen

[z31fanatic]

I have Mint 17.1 installed in triple boot configuration on a late 2013 Macbook Pro with the Retina display which has a native resolution of 2560x1600.

The windows, be it web browsers or any other window except settings, are too small and the text is super tiny. I have to zoom it to 200% in Chrome and Firefox to be able to read a page. While this works for the text, the window borders and icons are still tiny.

Is there a setting I am missing?

Which desktop environment are you using? HiDPI support is best in Cinnamon.

For individual applications you may have do additional steps. There are tips for browsers and such here: https://wiki.archlinux.org/index.php/HiDPI

I am using Cinnamon. Thanks for the suggestions, I'll give them a try.

HiDPI changed nothing.

[xenopeek]

I have no experience with HiDPI. Did you try the tips for Firefox and Google Chrome? https://wiki.archlinux.org/index.php/HiDPI#Firefox
For Chromium you'll have to build it from source to enable HiDPI support.

I tried those suggestions. Nothing makes a difference.
Lowering the resolution fixes the text but it messes up everything else.
It's disappointing because everything works fine with OSX and Windows 8.1 in the same computer.

Thanks for taking the time to respond.

z31fanatic,

Can you post some information. Use these commands in the Terminal:
inxi -Fx
xrandr

Then use this command to open the “Xorg.0.log” file:

Code: Select all

gedit /var/log/Xorg.0.log

Press Ctrl+A to select the entire file contents. Right click on the screen and select “Copy”. Don't save it to a file. Open the Mint Forum reply window and select “Code” in the menu. Paste the
copied lines between the two code words.

If you have problems posting that long file, then upload it to pastebin.com by using this command:

Code: Select all

pastebin /var/log/Xorg.0.log

Post the URL link that displays in the Terminal window.

The Xorg.0.log file shows the screen size being set is 677 mm x 423 mm, but the actual size is 286 x 179.

Code: Select all

[     8.768] (II) intel(0): Setting screen physical size to 677 x 423

To correct this, create a folder named xorg.conf.d in /etc/X11 by using this command in the Terminal:

Code: Select all

sudo mkdir /etc/X11/xorg.conf.d

Then create a file named 90-monitor.conf in that folder with this command:

Code: Select all

gksudo gedit /etc/X11/xorg.conf.d/90-monitor.conf

In the opened file, add these lines:

Code: Select all

Section "Monitor"
    Identifier      "monitor0"
    DisplaySize     286 179
EndSection

Save the file and reboot. If there is a startup problem, then at the GRUB boot menu select Recovery Mode. If no menu shows, then hold down the Shift key while starting, or keep tapping
the key. In the menu, select “root - drop to root shell prompt”. When asked for the root password, just type your user password. Then change the file permissions to read and write by typing:

Code: Select all

mount -o remount,rw /	

Then remove the 90-monitor.conf file with this command:

Code: Select all

rm /etc/X11/xorg.conf.d/90-monitor.conf

Then type “reboot”.
You'll go back to the Recovery Mode menu. Don't click anything, just wait about 7 seconds for the reboot.

[z31fanatic]

Because I have installed rEFIt boot menu, I can't see the GRUB menu so I can't go to recovery mode. Only options are to boot into one of the three OSes.

[roblm]

Did you have a startup problem? If so, then insert the installation DVD or USB drive. At the desktop, open the File Manager and select the correct Volume for your Mint installation on the left.
Go to /etc/X11 and right click on the folder xorg.conf.d and select Open as Root. Delete the 90-monitor.conf file.

Try testing this command to scale the objects on the screen to a larger size:

Code: Select all

xrandr --output eDP1 --scale .9x.9

You can test changing the value to .8 or less. To reverse the effect:

Code: Select all

xrandr --output eDP1 --scale 1x1

[z31fanatic]

I didn't have a startup problem. Scaling the objects to larger size improves text but it completely messes up the UI so I reverted back to 1x1. I guess I'll just have to deal with zooming to 200% until we have proper support of HiDPI in Linux.

Thanks a lot for your time. Very helpful.

[roblm]

Did the DisplaySize line in the 90-monitor.conf file make any change?

For your Macbook, in the Apple menu under Preferences, the scaled resolution of 1680x1050 should be available. I would think the image quality should look fine with that
resolution on a 13 inch screen.

[z31fanatic]

Did the DisplaySize line in the 90-monitor.conf file make any change?

None at all.

For your Macbook, in the Apple menu under Preferences, the scaled resolution of 1680x1050 should be available. I would think the image quality should look fine with that
resolution on a 13 inch screen.

That was the first thing I tried. Changing it to any of the scaled resolutions screws up the UI.

[Nick Payne]

I have a similar but not identical problem - I have two 80cm monitors running off a dual head nVidia card. One is an Eizo 4k monitor at 3840x2160 resolution, the other a Dell U3011 monitor at 2560x1600 resolution. In Cinnamon I can't find any way to size things on a per-monitor basis - having text fields, menus, dialogs etc at a comfortable size on the Eizo monitor means they are much too large on the Dell monitor, and if they're a comfortable size on the Dell then they're much too small on the Eizo.

The machine is dual boot with Windows, and in Windows I have no problem getting independant scaling on each monitor...

[roblm]

z31fanatic,

Does using this xrandr command to change the resolution to 1680x1050 give a better image than changing the resolution in the Apple menu:

Code: Select all

xrandr --output eDP1 --mode 1680x1050_60

To reverse:

Code: Select all

xrandr --output eDP1 --mode 2560x1600_60

EDITED:
The following information is from this web page:
https://support.apple.com/en-us/HT5266

I need a resolution for my external display that isn't on the list. Is there a way to get more resolutions?
Yes. Press and hold the Option key while clicking the Scaled button to see more resolutions.

Nick Payne,

This info is from the article in the link xenopeek gave in his post. Go down to the section > External displays, which says:

The HiDPI setting is desktop-wide so that non-HiDPI external displays show everything too large. One workaround is to using xrandr's scale option. To have a non-HiDPI monitor (on DP1)
right of an internal HiDPI display (eDP1), one could run:

Code: Select all

xrandr --output eDP1 --auto --output DP1 --auto --scale 2x2 --right-of eDP1
