@pier_andreit:

The effect may well be due to, insufficient GPU memory –

  • Check the BIOS/UEFI for a setting related to GPU memory related to Secure Boot – if you’re running in Compatibility Mode it may well be that, this setting cannot be activated …

This has nothing to do with memory or bios. This is total nonsense. This feature was introduced many versions ago for the SDDM login screen. https://phabricator.kde.org/T9658

You can try to switch the standard Breeze theme to anything other (for the SDDM login screen).

sorry for the wrong info, it is the lock screen that blur, and it isn’t due to memory, it’s a feature that there was also in the previous version of plasma but now is very more ugly

Oh, you mean the background of the lock screen is blurred when, you begin to type the password to unlock?

  • But, the field where the password is typed is sharp – isn’t it?

OK, if you have a nice scenic picture you took somewhere nice as the background, this picture becomes quite blurred when the password is typed –

  • On the other hand, one can then concentrate on the password field – which is quite OK for the large screen I’m using …

It could possibly be nice if, the KDE folks would include a setting to set the amount of blurriness to suit the taste of the user but –

  • Despite this issue being possibly worth a KDE Bug Report, the other part of the process is to influence the KDE folks to convince them a code change is needed …

Now on a Leap 15.4 Laptop –


Operating System: openSUSE Leap 15.4
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.90.0
Qt Version: 5.15.2
Kernel Version: 5.14.21-150400.22-default (64-bit)
Graphics Platform: Wayland
Processors: 4 × AMD A10-5750M APU with Radeon(tm) HD Graphics
Memory: 7.0 GiB of RAM
Graphics Processor: AMD ARUBA

Yes, the blurring of the Lock Screen is rather more than that with Leap 15.3 – in fact, a lot more than that of Leap 15.3 …

  • And no – I haven’t found a user setting to change the amount of blurriness … >:)
