How to fix screen tearing in LXQt?
How to fix screen tearing in LXQt?
I can't find a way to fix the screen tearing while using this GUI. On Xfce4 it's easy, I just use compton, but on LXQt, downloading compton and setting it to autostart doesnt do anything. I used the same autostart command like on XFCE, is that the problem? So what should I do, can anyone help? I like how the interface looks alot!

Re: How to fix screen tearing in LXQt?
I asume that you are on the 64 bit architecture. Did you tried one of these two drivers built for porteus:

I'm actually on 32 bit. I will try the drivers from the i486 directory and see if it works.francois wrote:I asume that you are on the 64 bit architecture. Did you tried one of these two drivers built for porteus:

I will let you know how it goes!

What is the nvidia card model that you have?

Re: How to fix screen tearing in LXQt?
Can you specify if tearing appears only on videos or 3D apps or all apps?
Also, please consider moving to Porteus 3.2.1 as version 3.1 is 2 years old. I've made a LXQt module for this current version, and with Nvidia driver I've managed to avoid tearing on all fullscreen apps -- there's just a little bit on non-fullscreen apps. I'm not using compton because I think it brings more problems that it solves.

Its an Nvidia 9300 GE. I am using Linux on an older machine, so the components are pretty outdated, but I tried it on my newer one with a GTX 750 TI and it's the same problem.francois wrote:What is the nvidia card model that you have?
I have to say though that I managed to fix tearing on XFCE, and MATE, so the graphics card should not be the problem. If I can't do anything, I guess I'l switch to XFCE, but I have been using that GUI on my Arch install for a year and I'd rather try something new. And I dont really like MATE, while KDE and Gnome run like garbage on that old machine.
PS: Trying different drivers didn't work.

Tearing occurs while moving windows on the desktop. Browsing and watching videos with Chrome works perfectly fine. However Firefox is unusable, the tearing is awful. But I am fine with using Chrome, so I guess that's not an issue. As for local video playback, VLC with 3D acceleration off works perfectly, but MPV and Mplayer tear. If I enable 3D acceleration on VLC in also tears.fulalas wrote:Can you specify if tearing appears only on videos or 3D apps or all apps?

So I think it might have to do with 3D acceleration, but I don't know why Chrome would behave differently then Firefox. I should mention that while the browsers are outdated on Porteus 3.1, I also experienced the same issue on a fully updated XFCE4 and Arch install. If I disabled compositing, then the tearing would behave the same as on the Porteus. Chrome and VLC work great, Firefox and MPV tear. Installing compton fixed all these issues. Since I am using Linux mainly to watch movies and just learn more about Linux, I haven't run into any downsides from having compton installed.
But I will try the new version and see what happens. The site recommended me that version for some reason, maybe because I selected 32bit. I will see into looking for newer versions even if they are 64bit. I will eventually use it on a better PC anyway.

If you could try XFCE, enable 'synchronize drawing to the vertical blank' on Window Manager Tweaks -> Compositor.AlexSmoke wrote:Tearing occurs while moving windows on the desktop.
I'll tell you what I'm doing to avoid almost all tearing on Porteus XFCE:
1- disable compositor
2- install Nvidia driver
This is enough for everything, except videos. For videos you have to follow this.
If you really want to use LXQt, I can only offer help for the new Porteus 3.2 version.
That's exactly my case 1 month ago and now I'm in love with Linux and PorteusAlexSmoke wrote:Since I am using Linux mainly to watch movies and just learn more about Linux

Re: How to fix screen tearing in LXQt?
Just an update on what I did. I gave up trying to make LXQt tear free, and instead moved to the newest 64-bit MATE version of Porteus, and I must say it's great! Looks really nice with the custom theme, it's faster then the old one and the browsers more up to date. Compton also works great. So I am glad I made this move!
In other unrelated news, I uninstalled XFCE4 from my Arch distro and replaced it with LXQt. On Arch, LXQt is up to date and compton works perefectly fine, so now I get to play with two new interfaces!
