RockPro64 linux console video mode - callegar - 09-06-2022 Hi, I have a weird issue with the linux console. I am trying to setup a rockpro64 and in doing that I am using an old Dell monitor with a 1680x1050 resolution. When the rockpro64 boots, the first thing that I see is the output from uboot. This is OK. Then linux is booted and for a short time I see a patterned screen. After this, there is the linux boot output. The issue is that as soon as uboot gives control to the linux kernel, the display becomes terrible: all trembling and slightly distorted. The monitor reports that the output is at 1400x1050@55Hz, which is obviously not correct. However, /sys/class/graphics/fb0/modes correctly shows U:1680x1050p-0. Obviously, I suspect that the poor display is due to using an output format that is not suited for the monitor. However:
Note that the issue seems to be cross-distro (tested with debian and manjaro). Thanks for any help, |
