Greetings KDE Community.
I am a seasoned Linux user of many years, my preferred setup being KDE on top of Ubuntu.
I’ve been working tirelessly to try and understand and resolve a seemingly intractable issue.
Using KDE (Neon) Plasma on top of Ubuntu, the following exists:
After leaving the computer for some time, the OS will enter/invoke a display energy saving mode. From this mode, mouse movements will wake it up, however the OS will NOT accept keyboard input to unlock the screen (i.e. unlock password). The keyboard IS functional as caps-lock, num-lock keys indicate they’ve been actuated.
I fought to resolve this issue for at least a year and a half with Ubuntu Studio, to no avail. I recently went to KDE Neon, which appeared to run ‘rock-solid’ and reliable for a couple of weeks, but is now experiencing a complete repeat of the symptoms above.
A few observations:
There may be a loose correlation between system lockup and pending updates, although I can’t really quantify this.
The use of a VPN (RiseVPN) may possibly exacerbate the issue, that and network connectivity.
All KDE installs have been performed with both newest and LTS versions of Ubuntu, and display the same symptoms.
Hardware can be ruled out. This same machine, running Linux Mint, operates flawlessly for weeks on end without issue.
In the spirit of community problem solving and desire to create and use the best possible open operating system, I put these questions/queries and frustration behind them to the Ubuntu/KDE community, hoping for thoughtful, considered replies toward solving this mystery.
