I got *new* laptop and did a clean installation of Linux Lite 6.6. Ran through the updates and so on.
Everything ran OK, even after a few reboots the same evening. Then the next day, I started the laptop and after login, the desktop launched OK, then suddenly the screen scrambled (multi-coloured horizontal lines), then blank. After a few seconds, the laptop rebooted. Again, logged in OK, desktop started OK, but this time it just went blank.
The next day (yesterday, relative to this post) I did a new clean install. That evening, all was well.
Home from work now, booted laptop and get the same crash sequence.
The only thing I can think, so far, is that during installation, I checked install third-party drivers, which required me to give a password for secure boot. It said that I would be asked for this password on next boot up. However, on both occassions, I have not been asked for the secure boot password.
I am now running this from the USB stick.
The laptop is a Lenovo ideapad 330 with AMD A6 processor and STONEY graphics.
How can I start looking for problem?
