[SOLVED]Laptop screen hangs and flickers Debian 9 and 10

Postby 4joeyirosh1 » 2019-07-02 08:29

Hi!I have a HP Pavillion Notebook laptop.Initially I had Debian 9 and about 2 weeks ago the laptop screen started to flicker,at times turn white and hang and I am forced to periodically bang the screen slightly for it to return to normal.I upgraded to Debian 10 and the issue still persists.

I am not sure if its a hardware or software problem but I would like to resolve this.

In my opinion, when manual hit corrects it, it is hardware problem...

Debian stable only gets security fixes (with a few exceptions) so if the problem appeared after the desktop had been working for a while then it probably won't be due to the software.
