checked again today. press physical eject button, tray opens, insert disc (tried blue man group audio cd, road to perdition DVD, Red alert 2 game cd, and karmic beta live disc from which I installed), close tray, drive spins up for a short time, no auto prompt appears, go to computer and attempt to select drive, dialogue appears stating no media in drive, attempt to eject at this point using eject cdrom command in terminal and the terminal hangs, kill the terminal and press the physical eject button and it ejects.
there is a different bug affecting many people mentioned at http://ubuntuforums.org/showthread.php?p=8060118 and https://bugs.launchpad.net/ubuntu/karmic/+source/brasero/+bug/438065 THIS IS NOT THE SAME BUG. this has been reported on both the acer 4810 and 5810 timeline series laptops. -- Cannot mount media in DVD rom drive, Acer Timeline 4810T. Drive is detected, and media only detected if placed in the drive when machine suspended. Even then DVD movies (purchased) are not recognised - error message that media is unknown. Audio cd's sometimes play. When trying to unmount, I am asked for my password - message given that another user mounted the media. https://bugs.launchpad.net/bugs/412527 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
