Hi all, In the process of helping install Ubuntu onto an Aspire 4810TZ, we found the problem that the DVD-ROM was not working (Ubuntu 9.10). After researching various web sites, found this one to be the most helpful. However, I was not too happy with the solutions presented. I discovered many of the above errors especially as described in the duplicate bug #438527.
So I found an alternate solution that I consider to be fairly simple -- at least this worked for the Aspire using the Matshita DVD-RAM writer UJ862AS. Since I am using grub to boot the multiboot system, I edited the /etc/default/grub file and changed the line as follows, adding the option noacpi: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noacpi" Ran update_grub and rebooted. After reboot, a "UDF Volume" icon appeared on the desktop for the DVD disk and was able to access its content. I am not sure if turning off ACPI will have any side effects ??? Hope this helps others. -- 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
