This *is* indeed a modesetting issue. It even works with the stock Ubuntu-21 kernel.
Boot option flag to nomodeset is a work-around to the issue. My conjecture: The card is attempting to be set outside of the displayable range (perhaps on a much higher resolution monitor this would not have occurred?). The test monitor maxes at a 1280 x 800 resolution, I believe. This seems not to be a kernel issue at all. If this is satisfactory, you may take whatever action you deem necessary and/or close the bug. -- ATI Radeon X1300/X1550 Series Video Card Problem https://bugs.launchpad.net/bugs/561983 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
