How to fix black screen on resume for Radeon

cn flag

Ubuntu works great on my Asus laptop, except Resume (after suspend) gives a black screen. I have seen many solutions but these are always for NVidia, while I have a Radeon chipset.

I also had, since the latest Ubuntu 20.04LTS updates, often a grey screen at boot, but fortunately could fix this by adding the kernel parameter nomodeset.

I tried kernel param: acpi_osi= but this could not boot at all. with acpi_osi="linux"

I did not try noapic or nolapic as the laptop is not that old (mid 2018).

The resume basically works, as I can log in from another system using ssh. The problem must be in the video. I am using the ubuntu radeon drivers.

I looked at https://wiki.cchtml.com/index.php/Ubuntu_Natty_Installation_Guide#Suspend.2FHibernation but I could not run Compiz Fusion, an error occurred and I was forced to log out.

I tried to restart graphics by logging in from another system and issue: sudo service restart display-manager but the screen stayed black.

Any help is greatly appreciated as suspend/resume would be very useful

Not a solution, but can you restart the graphic interface after resume by pressing alt-ctrl-f3 and then alt-ctrl-f2

I have Ubuntu 20.04 with Lenovo IdeaPad 5 Pro 16ACH6 (with the basic AMD Radeon integrated graphics card). The solution was to install the drivers from AMD website . i just downloaded the archive, run ./amdgpu-install and i got a bunch of errors but at the end of it all, it manages to resume successfully.

Disclaimer: I found this answer useful, but to be honest, I don't exactly know if this solved my problem. Reason is that I upgraded to Ubuntu 22.04. This was not easy, as the upgrade from 20.04 LTS to 22.04 LTS came as late as october 2022, so in april 2022 I had to do a fresh install of 22.04 LTS, with all the troubles of reinstalling all the extra needed packages

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.
