I recently installed buster on a machine so that I could install kodi on it for the purpose of playing Internet content on my lounge AV setup. It all worked fine with a regular monitor.
On trying to get it connected to the AV setup today, I get a rather strange problem. All text mode display is absolutely fine, but when gdm3 starts, I see a good mouse pointer, but all other graphical output is "torn up", in a way similar to the effect you would see on an old TV if the horizontal hold is badly out of adjustment. You can see my actual display here: https://imgur.com/a/0Vob8Na I would show you my Xorg log but there isn't one. At present I have only virtual console access to the machine. So, my question is, how can I resolve this problem? -- Phil Reynolds mail: phil-deb...@tinsleyviaduct.com Web: http://phil.tinsleyviaduct.com/
