[SOLVED] Visual errors caused by X screen blanking

Hello,

I am running Arch on an HP ENVY m6 laptop. After a certain amount of inactive time, the screen goes black, even if I am watching a video or otherwise need the screen to remain visible. I have already tried running the command

xset s off

and added it to my .xinitrc, but it had no effect.

In addition, sometimes the screen does not reappear properly after it has gone black. It produces an unusual visual error that seems to be a corrupted version of whatever was on the screen at the time. I noticed that everything still seems to function while the display is corrupted, and that opening a terminal and running

xset s activate

will usually restore the display to normal. How can I resolve this issue?

Hi,

Which graphics card does that laptop use?

Which graphics driver are you using?

Which desktop environment are you using?

Re: [SOLVED] Visual errors caused by X screen blanking

1. The graphics card is an AMD Radeon HD 7660G.
2. I am using the ATI driver provided by the "xf86-video-ati" package.
3. I don't use a desktop environment; I use the i3 window manager.

Re: [SOLVED] Visual errors caused by X screen blanking

That machine appears to exist in intel cpu and amd cpu flavors.
Please post full lspci output so we can be sure what's in your machine.

"xset s" only deals with screen saver settings, i think your issues are caused by dpms - screen blanking .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Re: [SOLVED] Visual errors caused by X screen blanking

After reading the wiki page on DPMS, I changed the "xset s off" in my .xinitrc to "xset s off -dpms". This seems to have resolved the issue; it appears that DPMS screen blanking was still occurring even though X screen blanking was disabled. Thanks for the help!
