TraceyC <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from TraceyC <[email protected]> --- I ran into a very similar problem with a similar setup - an HTPC (running CachyOS with Plasma) connected to a TV over HDMI as the only display. The details leading up to the result are a little different but the result was the same - a blank display and no easy way of recovering. Note: There are ways of recovering which don't require reinstalling the system, but that's tangential. The user should have an easy way to recover from the situation. Details: - The TV was turned off, and the system was left on (no sleep / hibernate) - Due to some problem we haven't gotten to the root of, after turning on the TV, sometimes the backlight would come on but not display the desktop. Sometimes, the desktop would be in a corner of the TV display. - To get the display back to normal, if the UI is visible, we go to Display Configuration - choose a lower resolution, apply, choose the correct resolution, apply. **However** one time, I chose a resolution the TV couldn't display. It went blank and then showed a message (from by the TV) that the resolution was not supported, and to choose a different resolution. Note: I had not clicked Keep. I expected that when the timeout was reached, and the change was reverted, that the TV would display the desktop again, but this didn't happen. This got the TV into the same state as described in the first comment. In situations like this, it would be nice to have some sane fallback that allows the user to regain access to the UI and recover In the Windows world, when a graphics driver crashes, the UI is able to fall back to a very low / basic resolution (usually 800 x 600), so something like that would be nice. Workaround: Get to TTY and reboot -- You are receiving this mail because: You are watching all bug changes.
