Possibly not. I haven't tried vgasize= for years and there have been a lot of changes to the firmware & videocore mailbox interface since then. Plan 9 should accept whatever resolution comes from the gpu, so it may be the firmware which "forces" 1920x1080. Maybe gpu_mem needs to be bigger than the usual 16, or some other config.txt adjustment is needed? ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T83b43600a3d592d7-M454fc86bb92c603c4343b624 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
