I'm afraid I no longer have access to the hardware needed to reproduce this bug (and I doubt running recent versions of Ubuntu on hardware supported by viafb is something many other people do, either).
Please do whatever's necessary to reflect that to this bug's state, assuming leaving it permanently incomplete is not desirable (I wanted to mark it "Won't fix", but launchpad won't let me). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/562494 Title: viafb and vga16fb turn off lcd on an acer aspire 1350 Status in “linux” package in Ubuntu: Incomplete Bug description: After upgrading from karmic to lucid my laptop turns off its lcd panel early during boot, after which I cannot figure out a way to turn it back on. X starts (I can hear the gdm drums and log in blindly), I can ctrl+alt+f1 out of X and alt+f7 back into X, but during all this I get no output on the screen. Blacklisting the viafb module gives me a garbled framebuffer. Blacklisting vga16fb too makes everything work. Fixing this is a little annoying because just disabling X still does not give you a working shell (I used a rescue cd to edit /etc/modprobe.d/blacklist.conf). So it might be nice to fix this before lucid is released, even if it involves disabling viafb on more systems than strictly necessary. I'd be happy to test any patched kernel images that might avoid this bug.
