When I move my mouse cursor with touchpad from time to time (it’s very noticeable) my cursor stops moving. It freezes.
I usually use KDE plasma but I have problems with scaling there and I have touch screen in my laptop so I would like to give Gnome a chance.
I thought that It can be Wayland fault but In plasma Waland there is no problem.
Please read this: How to provide good information

Now we know the symptom of the disease, but we need some more probing to know where the origin lies…
An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.
Yes it is the live system. But problem was the same in regular one.
I currently use KDE edition which is my favorite distro. Sadly in kde I have problem with scaling (its hidpi laptop).
Firefox is blurred (I managed to fix this)
Libtroffice don’t scale well.
And the worst is the problem with Virtualbox. Main window and guests are blurred.
Because of this gnome seems the best option. Firefox work out of the box, libreoffice has blurry interface but I have to live with this, and most importantly virtualbox works almost ok. Main window is sharp. Guest machines don’t have scaling but maybe I will be able to find the solution.
I don’t want to have two DEs so I can create system snpshot, install gnome and check how it work with other kernels
Any update on this?
I seem to have the same problem on a brand new LG GRAM 16: I’ve installed Kubuntu and everything runs smooth, today I tried installing Manjaro GNOME and I see this evident lag when I move the touchpad. I tried both with X11 and Wayland and I basically see no difference
Not the perfect solution because I have HiDPI screen - problems with Firefox (was able to solve it), problems with LibreOffice and Virtualbox.
LO problems I was able to partially solve, but with VB I couldn’t find the solution.
Nothing new I’m affraid.
On Gnome I have lags. On Plasma, I have HiDPI issues.
I use computers for… a very long time.
There is something like native resolution.
If a screen native resolution is for example 1024x768, and you set it to 800x600 then everything on the screen is going to be larger but 800x600 is going to be upscaled to your screen size and that will produce a blurry picture.
This is what you want me to do?
p.s.
I wanted to change resolutions just to be sure that it actually is blurred. But I can’t.
In Plasma settings I can change with scaling set up to 200% then the thumbnail says that resolution is:
1128x752
When I change the scaling to 100% then “Laptop screen” shows 2256x1504
And I can’t choose anything in resolution setting
So on a laptop screen: most of the time, as they mostly only support 1 native resolution
On an external monitor: no, as they support multiple native resolutions:
E.G. in the below 3-monitor set-up:
xrandr -q
Screen 0: minimum 320 x 200, current 4480 x 1080, maximum 2560 x 2048
VGA connected 1280×768+1280+0 (normal left inverted right x axis y axis) 370mm x 222mm
1280×768 59.9*+
1280×960 60.0
1280×720 75.0 60.0
1024×768 75.0 72.0 70.1 60.0
832×624 74.6
800×600 72.2 75.0 60.3 56.2
640×480 75.0 72.8 75.0 66.7 59.9
720×400 70.1
LVDS connected 1280×800+0+0 (normal left inverted right x axis y axis) 380mm x 216mm
3840×2160 144.0
1280×800 60.0*+
1024×768 60.0
800×600 60.3
640×480 59.9
DP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 382mm x 215mm
1920x1080 60.02*+
The VGA monitor is running at 1280×768 instead of 1280×960 (its maximum)
The LVDS is running at 1280×800 instead of UHD (“4K”)
The laptop screen is running its only resolution it has.
Butglxgears running on all 3 monitors is the same physical size.
If that is not good enough for you, xrandr has some scaling options as well:
--scale x[xy]
Changes the dimensions of the output picture. If the y value
is omitted, the x value will be used for both dimensions. Val‐
ues larger than 1 lead to a compressed screen (screen dimension
bigger than the dimension of the output mode), and values less
than 1 lead to a zoom in on the output. This option is actu‐
ally a shortcut version of the --transform option.
--scale-from wxh
Specifies the size in pixels of the area of the framebuffer to
be displayed on this output. This option is actually a short‐
cut version of the --transform option.
But you need to take a mathematical approach to your issue:
measure the physical size of your monitors,
divide by the number of pixels and then you get your DPI. (Dots Per Inch).
then scale down the highest resolution monitor so that it coincides with the lowest one.
Please note tha scaling can do only so much, so if you have a 31" FHD TV and a 13" UHD laptop, no amount of scaling is going to get you a satisfactory result: you have to sync your purchases to their physical constraints.
Actually I haven’t spoken about HDPI myself, but since you mention it, I found out that on this LG GRAM 16, the default resolution 2560x1600 (16:10) is not really manageable on GNOME: I can set the font scaling to 1.50 and that would be fine, but then QT applications (e.g., Kate or Albert) get really too big. Setting the font to something less makes most things unreadable. The solution I found was to set the resolution a little bit lower 1920x1200 (16:10) and font scaling to 1.30. With that, everything looks fine and I see no real blur with this lower resolution.
Comparing that with KDE (again Kubuntu, but I guess that’d work also with Manjaro KDE) I can leave the resolution to default one and I set the scaling to 175% and everything is fine (also with GTK applications).
Once again, looks like KDE can handle HDPI better than Gnome
