CD/DVD Rom not working in Ubuntu 8.04 on Lenovo Ideapad Y710

Yes Correct,
The mount showed above is from the VM.
The actual Ubuntu installation does not creat even the device in the /dev dir. It seems like do not see it at all , like is not there while booting.

Interesting this problem is NOT unique to you..

I can confirm that this also occurs on a new Lenovo IdeaPad Y710, which has an IDE connected Optiarc DVD RW AD-7560A. I was able to boot the install CD for the 64-bit version of Ubuntu 8.04 and install went fine, but the DVD/CD drive is not even seen after the initial reboot. Oddly, when booting the PC, the disk drive activity light stays on constantly until the CD drawer is opened - it then acts normally.

I don't even get the /dev/scd0 device, and I can't find anything in the DMESG output or the system logs that is meaningful to me.

I've tried the all_generic_ide=1 and that made no difference. I even set the region of the DVD drive (from the preinstalled Vista partition) to 1 and that did not make any difference either.

I'm thinking I might have to go back to Gutsy, or maybe even find another distro (nah, just kidding) - I really need to have a working CD/DVD/R/RW drive...

I believe this guy has a different problem than the bug thread he posted in but the symptoms look like what you are experiencing.

another report is here.. http://ubuntuforums.org/archive/index.php/t-925803.html

This looks like it may be a bug in Ubuntu with your hardware.. (the VM install doesn't really count because it's simulated hardware)

Have you tried any other Linux Distros on this hardware ?

Hello,
I found that post in the Lenovo support forum.

I found a solution, mi CD/DVD unit doesn’t work after I install Fedora Core 8 and It was not possible to see it form Windows and from Linux, but in the web I found that someone has the same problem he or she fixed, and has the solution but in linux and is: that in the grub.conf in the line where says Kernel…….. put acpi=off. It works now I can see my CD/DVD unit in linux but I still can’t see it in Windows….. ?

Under ubuntu there is no grub.conf file. I wanted to give a try to the option acpi=off and see what it will happens. I can't find thr conf file. The above post is for FC8.

You should be able to find grub.conf at /boot/grub/. Also after reading my last post it just hit me that I should probably clarify that I was really surprised that I found that many people with similar problems. So please don't take it Like I was being a smart a**.

grub.conf is probably /boot/grub/grub.cfg on Ubuntu

PiraeusStef · 12-05-2008, 08:45 AM

No , no worries.
I believe (after I contacted Lenovo support ) that the are awared of the problem but since is not the pre-installed OS they do not want to help.
They help me although to get around on the Vista problem with the DVD.
After I installed the Ubuntu in first place I lost CD/DVD in both Vista and Ubuntu. And there are a lot of people with the same problem.

About grub.conf There is not one anywhere ( I did #find / -iname grub.conf) and returned nothing.

Can I manually create the file.? I noticed that my VM-Ubuntu does not have also. Is that strange. Can this be the mother of my problem.

Thanks again for your time.

there is no grub.cfg either.

farslayer · 12-05-2008, 09:11 AM

Maybe your distro is still using /boot/grub/menu.lst for the menu options rather than the grub.conf file.

http://wiki.linuxquestions.org/wiki/Grub.conf

Quote:

The default location is in /boot/grub/menu.lst. The .lst suffix stands for menu list, not menu first. The file contains configuration options (like default boot entry, (grub.enbug.org) color, timeout and password settings) and a list of menu entries. The file is often managed by some tool from the distribution itself, so when kernels are installed or removed the boot menu list gets automatically updated. Another common location is /etc/grub.conf but this is often a link file to the /boot/grub file.

Okay it worked. I have add acpi=off in the Kernel load command and the DVD/CD mount without problem.
I got some error messages on the boot regarding my BIOS.

kernel /boot/vmlinuz-2.6.24-22-generic root=UUID=889c5cee-fae3-440a-beba-9dec970a426b ro quiet splash acpi=off

Case Solved
I will do some more testing.

Thank you very much both of you.
