Dear Maintainer, Attempted to install Debian 11.0.0 on AMD Ryzen 3 2200G ASRock A320M-HDV motherboard with VGA connected NEC EA231WU 1920x1200 monitor. Both the netinstall and DVD-1 images booted but each produced a shredded raster display for both the graphic and text install options.
Hi Mike, Mike Perrin <mperrin@icehouse.net> (2021-08-16): Please check the installation guide, we'd be happy to have some feedback regarding the proposed workarounds: https://www.debian.org/releases/bullseye/amd64/ch02s02 https://www.debian.org/releases/bullseye/amd64/ch06s04#completing-installed-system Cheers,
Cyril, Thank you for the prompt reply. I had read those pages and was using the firmware-11.0.0-amd64-DVD-1.iso and firmware-11.0.0-amd64-netinst.iso images. But I was unable to even begin using the installer. Attached are photos of the DVD-1 boot screen and resulting displays when choosing the graphic and text install options. The results with the netinstall iso were identical. I was able to install 11.0.0 using the debian-live-xfce+nonfree iso and the installed system works just fine with my NEC monitor. I tried using the i386-netinst.iso to load 11.0.0 on an ALIX 1C Geode embedded board. My NEC monitor refused to display giving me a "VGA out of range" message. When I tried an Acer AL1717 1280x1024 monitor the netinstall came up perfectly. Mike
Cyril, Out of curiosity I downloaded the 10.10.0 netinst.iso and tried it on my system. It produced the same results as 11.0.0, the installation display was shredded. I had installed 10.0 on that machine when it was released with no problems but was using a Samsung 204T 1600x1200 monitor at the time. It seems there is something wonky (or at least uncooperative) about my NEC monitor. Mike--------------------------------- Cyril, Thank you for the prompt reply.

Cyril, I may have a clue as to what is going on. I tried booting Clonezilla Live at 800x600 resolution and got a similar shredded raster image as with the Debian installer. Then I booted Clonezilla with the 1024x768 option and the display was perfect. Mike
Cyril, When I boot the DVD-1 on an ASRock Q1900M Pro3 Celeron J1900 board my NEC monitor is perfectly happy. The selection screen comes up at 640x480 and both the graphic and text installers appear at 800x600. However when I boot the DVD-1 on my AMD Ryzen 3 2200G machine the selection screen comes up perfectly at 1920x1200 but the monitor still thinks it is getting 1920x1200 with both the text and graphic installers. The attached photo shows the information displayed from the monitor menu on the shredded text installer screen. It would seem the problem is not my monitor but is related to the installer's interaction with the built in Radeon Vega graphics of the 2200G APU. DVD-1 produces 1920x1200 for the selection screen but something goes wrong when the graphic or text installation is started. Mike
produced a shredded display at 1920x1200.
