suddenly no graphics?
I've been running Linux Mint for a while & it has been reasonably stable since I did a clean install to 18.1.
I have 3 displays on an ATI HD6670 (DVI, HDMI to DVI & Dp to DVI adaptors). After faffing round for a while I got these running OK & they have been for months. I turned the PC on the other day & got a black screen after boot. It was working fine the night before & I didn't play with anything. Sometimes I get the grub menu with my boot options, usually not. Previously it sat at grub waiting for my input, now it goes onto loading LM then goes black. I can get a command line. I can boot OK into W7 & a live disk - the graphics card seems to be OK. So I'm thinking that the graphics driver has gone bad somehow. I've seen this sort of stuff: Code:
[drm:radeon_dp_link_train [radeon] *ERROR* channel eq failed: 5 tries but it doesn't appear to offer me much. What are the options/procedures for resolving this either from the command line or copying drivers from the live disk? Many thanks Update I just suddenly got the grub options & booted into my old LM17 OK but with no DP option. I disconnected the DP adaptor & rebooted & am now into my LM18 system. So, how can I tell if the system has a corrupt graphics driver/element or if it's a hardware issue? Cheers |
Do not have solving answer for you, but from search this bug appears to look similar to your case: https://bugzilla.redhat.com/show_bug.cgi?id=1353341. From reading there, think that it might be that you will need older, or newer kernel. Hope that it can help you a bit.

Is it possible to roll back the kernel update? |

but usually old kernels are not removed for these precise reasons. not sure if mint/ubuntu also do it like that; if they do you probably still have a few old versions floating around. if not, i'm sure it's a mechanism that can be switched off (the automatic removal of old kernels i mean). |

ONDOHO, Apologies, I try not to use colloquial language on here, but this slipped through. "woolly" means vague or confused - I know that the kernel is a core part of the OS but how it functions & what it controls I don't know. "aggro" means aggravation = problems and difficulties: like having to spend hours learning about kernels, tracking down which one I have and then deducing which one I need to reinstall & how to do it. It looks like there are other kernels that haven't been deleted - how can I tell if they are still actually there? What will a kernel name look like and in the update manager there is a list and it looks like I have the option to install any of them I appreciate your help chaps & am trying hard not to leak frustration!

or uname -a on console to find out, which kernel you are running.

kernels (and associated packages) start with 'linux-' and use a versioning scheme that leaves no space for unclarity. |

Things have taken a twist as I installed Timeshift to take a snapshot of my system before playing with the kernel. Unfortunately, It runs out of disk space & won't save to my 2tb NAS. In the meantime, it seems to have eaten any disk space I had (or coincidentally, my disk became full). So now I'm trying to resolve this |
it sounds like you should start a fresh topic, explain the new/changed situation?
