I mean, the graphical login was visible, the black screen was happening after logging in.<br clear="none">I tried different desktops, that were installed: Gnome 3, Unity, LXDE, Xfce, but i was always getting black screen. I don't know, why it happened. Possibly, something got updated and it caused this problem.<br clear="none">It happened about a 2 months ago. After spending a couple of days troubleshooting it, nothing helped, so I desided to do the unthinkable, upgrade my LTS 22.04 Ubuntu to the latest version, that was at the time 23.04. It fixed the black screen, but the picture became overexposed:<br clear="none">[Inline image]<br clear="none"><br clear="none">I tried to install drivers from different unofficial repositories, but none of them changed the situation, so I returned the drivers from the official repository.<br clear="none">I tried using xrandr and other utilities to change contrast, brightness and gamma with using reference pictures for adjusting those values, but it didn't help. White range was still cut off after certain value, but it just became more dimm, when I tried to lower those values and lower range of blacks was cut off on the lower range even when trying to raise those values.<br clear="none">The only time, when picture became normal was, when I loaded LXDE and openbox:<br clear="none">[Inline image]<div class="yqt0892557689" id="yqtfd22214"><br clear="none"><br clear="none"><br clear="none">Gnome 3, Unity and Xfce were openexposed.<br clear="none">I tried to do: openbox --replace after loading different DE, but it didn't work with Gnome 3 and Unity, but it worked on Xfce.
