With the i810 driver, the use of vbetool during suspend/resume causes the display rendering to be a mess after resume. I have had to comment out vbetool from the suspend.d ACPI scripts. I am going to file a separate bug report about the need to remove or fix the use of vbetool. I don't know if this is a vbetool bug, an issue in the i810 driver (Alan Hourihane seems to think not) or some other issue. I also don't know whether the use of vbetool is required for other video chipsets. I suppose the use could be special cased. Lastly, I suppose it could be an issue in the Linux kernel's ACPI support. -- Regression: Hibernate with radeon driver -> garbled screen https://launchpad.net/bugs/44961 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
