Font scales With HDMI screen ratios

[phonic-otg]

Hello Fellow Kubuntarians

After recently moving from VGA to HDMI on a full HD-1080p TV I had noticed that Fonts were no longer legible (all too small) My workaround by changing the font settings in System Settings> Application Appearance> Font and changed the font size to one that was acceptable (around 26/28pt for 1280x720p & 48pt for 1920x1080p . That worked for most applications and the desktop but...

...Then dolphin had font issues that were rectified with dolphins in built font settings (pheww).
Alas though Libre office still has issues with the General Font size (especially the menue bar font being super large) as does Kmail fonts being too small again but unlike dolphin lacks adjustable font settings that fix my issue...

...Has anyone else also experienced similar?

Cheers
Phonic.

What's your DPI setting? You can look in /var/log/Xorg.0.log or run this in a terminal:

xdpyinfo |grep res

Thank-you for taking an interest.

xdpyinfo |grep res

Gave out...
...

phonic@Nova-Fractal:~$ xdpyinfo |grep res
resolution: 29x29 dots per inch
KeyPressMask EnterWindowMask LeaveWindowMask

.................................................. .................................................. ....................
My current resolution 1920x1080 has small fonts being too small to read (anything under 16pt).
I'm wondering if I can modline some new ones as the next size down is 1280x720?

Well, it's square, but that's really a low DPI IMO. Try this: In a terminal type;

xrandr -dpi 100

and report the results.

Here are some screen snaps of fonts forced @96DPI ss0 to ss3...




...and ssa0 is the 3 mentioned programms without DPI forcing. (keep in mind dolphin has its own in-built font setting(yay))

[oshunluvr]

Sorry typo! Should have been two dashes in front of dpi


xrandr --dpi 100

[oshunluvr]

BTW, those are the oddest screenshots I've ever seen.

[oshunluvr]

Also - 96 DPI are the Windows font sizes. Xorg fonts come in 75 and 100 DPI.

[phonic-otg]

Ok did xrandr command, @75 had little effect so I reset the default fonts and it all reverted to very small (exept libre office reverted to perfect font scale-go figure) this is what it looked like ....
...

See how it all goes very small even dolphin with internal font control, as well unreadable wallet pop up.....

Looks like I need to do some heavy research.

xdpyinfo |grep res
gave
phonic@Nova-Fractal:~$ xdpyinfo |grep res
resolution: 32x29 dots per inch

[oshunluvr]

Did anything happen when you did the xrandr --dpi 100 command? The screen should blank for a second and then come back. I tested it at home before I left for work this morning, and it had the expected effect for me.

Run the xdpyinfo command before and after the xrandr command to verify it took.

[phonic-otg]

I did as sugested and performed the

xdpyinfo |grep res

first (which gave a res of 32x29 then

xrandr -dpi 100

then

xdpyinfo |grep res

again which gave 100x100 res. I

sudo reboot

-ed and noticed on the login screen, that the fonts were still out of whack, as the word "login" is super huge and the user and password are super tiny. The session goes to my first desktop where the widget text seems right as does the text in the panel and start tray aswell the clock. Firefox text is fine too. I then open a terminal and

xdpyinfo |grep res

again which gave me 32x29 again so it seems it did not take. I've checked System Settings> Application Appearance> Font and they are all set to 32pt still.
I'm attempting to do it again this time with the fonts reset to their defaults.
I'll post the results.

[phonic-otg]

The result.
phonic@Nova-Fractal:~$ xdpyinfo |grep res
resolution: 32x29 dots per inch
KeyPressMask EnterWindowMask LeaveWindowMask
phonic@Nova-Fractal:~$ xrandr --dpi 100
phonic@Nova-Fractal:~$ xdpyinfo |grep res
resolution: 100x100 dots per inch
KeyPressMask EnterWindowMask LeaveWindowMask

I logout and back in with fonts set at there defaults...

The real result in screen snap (res-1280x720p)









Also after all that the xdpyinfo |grep res reverted to 32x29.

I guess I should have explained: rebooting or logging out will always reset your video to it's default. The intent of the xrandr command is to see if it fixed the problem before a permanent solution is set.

At this point, I still don't know if changing your DPI fixes the problem because you keep cancelling it out by logging out or rebooting.

Please enter the command, verify it took (seems like it is) then don't log out or reboot and check your fonts. You'll want to re-set them to a normal size to see how they look.

Once we determine it works - then we'll make it permanent.
