Programs with wrong resolution and reverse scrolling not consistent

#1

Post by Nez » Fri Jun 14, 2019 4:59 pm

Hello,

I've install MX Linux yesterday but I'm having a few annoying issues.

Some programs start with a weird resolution. My screen is FHD. Here is what KeepassXC and QownNotes look like

There is an option for natural (reverse) scrolling but it doesn't work for many programs, including many MX Linux programs. From what I understand, XFCE allows natural scrolling but not in GTK3 apps ... ?
I have tried with both Synaptics and libinput drivers.

Hmmm...those are Qt 5 programs. Some people have had similar problems with other Qt 5 apps like vlc that they've solved with an environment setting, but I have to run and don't have time to look it up--does anyone else remember it? If it's not in the wiki, it would make a nice addition for Troubleshooting.

Maybe this? viewtopic.php?f=108&t=48785
Or the thread on VLC? viewtopic.php?f=104&t=49555

Both those mention using qt5ct and setting environment variables. A search for "qt5ct" brings up 8 pages. qt5ct is a configuration tool for QT5.

This person was having the opposite problem where VLC, another QT5 app (I think), was too big compared to Xfce and other non-QT apps, but the the solution should be the same only with different values:

Thanks for the answers.

I figured they were both qt5 programs but couldn't find a fix.

Also a few hours after writing the post I got fed up and installed another distro then went to bed. I shoud've deleted the post, sorry.

It was probably a simple matter of installing qt5ct then increasing the size of the fonts. A web search would have probably shown you that as a solution.

FYI none of us here get paid to do this as our jobs. We're just fellow-users for the most part, volunteering to try to help others just like with most distros' forums. If you expect near-instantaneous responses to your technical questions you'll need to switch to a Linux distro that offers a paid tech support model such as RedHat or the commercial SuSE and sign up for a support plan.

I hope your chosen distro makes you happy.

Or have a look here:
VLC runs without interface

Just test it manually from the command line like this:
VLC:

Code: Select all

env QT_AUTO_SCREEN_SCALE_FACTOR=0 vlc
KeePassXC:

Code: Select all

env QT_AUTO_SCREEN_SCALE_FACTOR=0 keepassxc
Probably the simplest fix to add manually to /etc/environment like

Code: Select all

echo export  QT_AUTO_SCREEN_SCALE_FACTOR=0 | sudo tee -a /etc/environment
or alternatively add to

Code: Select all

/etc/X11/Xsession.d/56xfce4-qtconfig

What would a Wiki entry contain, exactly? I mean, what general problem would it be addressing? Should it be, for instance, a post in the Applications section?

Not sure I get this whole question...
Production: 4.15.0-1-amd64, MX-17.1, AMD FX-4130 Quad-Core, GeForce GT 630/PCIe/SSE2, 8 GB, SSD 120 GB, Data 1TB
Testing: AAO 722: 4.15.0-1-386. MX-17.1, AMD C-60 APU, 4 GB
Personal: XPS 13, 4.18.0-19.3-liquorix, 4 GB

That's not what I meant. I was tired of searching. Response on the forum was great - and even if it wasn't that wouldn't be a problem. I have nothing but admiration for people who make linux distributions.

I like what I saw - the smart install, the tools, the great battery life. But this kind of issues I had after install will discourage normies like me.

I might try again when I have more experience.

@fehlix: thank you

My point is you only posted about your computer issues today and you've given up already. Even so-called "normies" as you put it have to learn a bit of patience when asking for help with an operating system which cost them nothing. Many of us live in different time zones, for one thing, and may be sleeping when you initially post.
