My mouse's cursor has started going invisible in X

RandomTroll · 05-13-2016, 01:57 AM

A few days ago the mouse cursor started going invisible in X. It still exists: I can 'choose' whatever it's on, I can mark a portion of the screen. It's invisible in Firefox, an xterm, Acrobat - any app I've tried. I'll switch to an xterm and move it around for a few seconds until it reappears. It works properly outside of X. I upgrade the kernel every new (stable) version, check for updates to Slackware daily, can't think of anything unusual I've done.

Not in slackware, but I had this happen to me when I had my video rendering set to use EGL instead of XGL using an Intel gpu.

How does one set 'video rendering'? I don't see it in /etc/X11/xorg.conf or its inclusions.

I already know I have an Intel GPU; I don't know how to specify EGL/XGL

If you're using KDE, it's in the control panel for KDE. Not sure how it would be set for anything else, since KDE is my preferred DE.

I don't use any desktop.

how fortunate that you deigned to share that knowledge with us, your humble servants!

neither do i.

however, a quick search for your symptoms lead me to this and the suggestion to use a newer kernel.

if that doesn't help, we will really need a little more cooperation from you.

There's a ton of stuff to know. Instead of flooding my post with everything possible I anticipated questions that would ask for relevant info.

Mr Timothy Miller raised the issue.

I update my kernel every version change.
