Black screen on HP EliteBook after lock or reboot

ls flag

After an Ubuntu 20.04 security update on HP EliteBook 840 i7-8550 I did a reboot. The GRUB works properly, however I get black screen afterwards. I need to use recovery mode and only then switch to the normal boot to get my Ubuntu working. Moreover, the same issue happens after locking the screen either due to power saving or doing so by hand. It seems that once the screen goes black it does not recover. Where should I begin to solve this problem?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
