Puppy Linux Discussion Forum

Just frugal installed Puppy F96-CE and loving it, but I get screen tearing when scrolling or on videos, so I know on Ubuntu distros you alter the xorg files to turn on no tearing but in my puppy files I see no xorg conf for intel at all, I'm not that proficient in bash so I hope I'm describing my problem well enough so you guys can help me. Again, Intel GPU, screen tearing on video playback. Probabky just need to create the conf file but syntax is always very specific so if anyone knows exactly how to help with detailed instructions thank you soooooo much in advance!

@PunchyMchurtyfist - Often the default video driver is modesetting (unaccelerated). You could try the intel driver - I found it reduced tearing. My Method: (need to use arrow keys & enter to select items)
Exit X windows (ctrl-alt-backspace), then type xorgwizard & press enter, then select set video driver, then select specify & type intel, then ok, then done, then type xwin & press enter. Hopefully that will improve things.

It would help if you post what is provided by Pup-Sysinfo ->Devices ->Display ->Summary

You can highlight and copy from Pup-Sysinfo and paste into a post.

This will tell us what driver you are using and other info.

Information about the computer will help.
Make and model?

Try this.

You will need to be booted using a save file or folder, so this can be saved to always get used on boot up.

In /etc/X11/xorg.conf.d/

Add this file:

Reboot making sure save is updated.

Any help?

It did fix the screen tearing issue but it also changed my screen resolution to a very strange setting, is it any way to have the screen tearing option but not whatever changes the resolution

What did it change resolution to?

Is it maybe the (native) default resolution of the monitor?

Did you try to use the programs for setting resolution and change it to what you want?

What resolution do you want?

I have a Thinkpad X220 with a similar issue. Try to install and run a compositor like xcompmgr, otherwise you'll get tearing with X.Org. I don't recommend changing drivers or playing with xorg.conf because X.Org is largely deprecated and modesetting is your best bet with Intel graphics (xf86-video-intel is deprecated).

(With Wayland I don't get any tearing on this laptop.)

It may have been my monitor's native resolution as I have my laptop connected to a large tv, the resolution I use is 1280x1024 but when I pasted the file you gave me and saved it, it also changed that resolution and I could no longer change it back to 1280x1024.

EDIT: I believe I got it! I'm new to Puppy and it feels kind of convoluted to do anything compared to Ubuntu distros, but I've successfully integrated the file you gave me and managed to change the resolution back to what I had it originally so I think I'm good now. Thanks for the help and the patience for a total noob.
