Hello,

I'm using Slackware 14.2 as my main OS, running on a notebook with an external monitor, notebook monitor disabled/closed.

Never had to configure my monitor, it worked on full resolution since the first boot, never had to configure anything. It's a intel based notebook.

Today the resolution is capped at 1024x768, i reboot everyday.

- It's updated to current, there was xorg updates but it was weeks ago, problem started today;
- Haven't configured/installed anything since the last update.

I'm running a server, could my system be compromised by a hacker? PHP is capped and i have mod_security configured and enabled.

I tried slackpkg reinstall xorg and xf86-vide-intel
Also tried deleting xorg.conf-vesa.

I doubt a hacker would care about your video resolution.

Are you using a desktop environment? If so, which one.

What is your graphics chipset?

Have you looked at /var/log/Xorg.?.log? That may give you some hints.

These days, X has gotten so stable that it no longer needs an xorg.conf by default. However, if you wish to create one, there is a way to do so. This link may help: https://docs.slackware.com/slackbook:xwindow_system

As frankbell said, you do not need a xorg.conf unless you are using a proprietary blob like nvidia drivers. If you do have a xorg.conf it should only have the few things you want to change, for example mine configures xorg to use DRI3 instead of DRI2.

My guess is that you used a game or other program with lower buggy resolution that forced it for xorg as well, alternatively there is something in your xorg.conf that did not work as you expected with a newer version of xorg. You can reset it with something like 'xrandr -s 0' or set it a specific resolution with something like 'xrandr -s 1680x1050' where you should enter your desired resolution of course.

Indeed, it makes no sense. My concern is what behind the scene event caused the issue.

How do you know that's my desired resolution? Are you the hacker? SlightlyScaredSmileFace

I'm trying to remember, i switch between KDE and XFCE and i did tried running KDECompare while on XFCE, it had a very poor interface.

bash-4.4$ xrandr -q

bash-4.4$ xrandr -s 1680x1050
Size 1680x1050 not found in available modes

try xorgsetup

I'm closing the thread because it's boring for people to care about other people resolution but it's an issue and i will leave the final thoughts:

How i got my resolution back:

Is it working like before? NO!

- Normally when slackware is booting the resolution is low and then at some point it loads the right resolution and the text gets small, cause of the right resolution.
> > Now when slackware is booting it jumps from the low resolution to a slightly better resolution, but not still a low resolution.
- Then it goes from text mode to SDM login screen and i have the full resolution.
> > But when i login the resolution is 1024x768 again and i have to manually select my full resolution.

Something happend.

I had the exact same problem happen a week ago or so on a computer I maintain. No installations or updates were done prior to the problem. There was just suddenly a maximum resolution of 1024x768. After trying a number of things I ran xorgsetup and that fixed the problem. Unlike the xrandr solution above the fix persists after reboot.

Lol, it was an arbitrary example where I used my screen's resolution.
