(previously vclio256) Having looked into this further I am willing to suggest a solution for those affected and can say that I don't think it is a problem with xserver-xorg-video-ati but is due to the kernel that is in use. After doing a full install of Ubuntu 14.04 (Trusty Tahr) Daily Build and putting back the original kernel which comes packed with the iso resume works as expected. Here's what I think is going on:
To boot a fairly recent version of ubuntu (12.04 and later) requires a machine with a PAE capable processor. Many machines which included the Mobility Radeon 9600 M10 (RV350) such as the Dell Inspiron 8600 contain older CPUs, such as the 32-bit Pentium M 'Banias', which do not support the PAE extension. Therefore in order to boot these machines requires a non-pae kernel. I believe these kernels are the source of the problem, at least with newer installs, as they are often mismatched with the rest of the system. The solution is to replace the version of the kernel used to boot the system with the PAE version that is packaged with the distribution. To do this on a system that doesn't support a PAE kernel you will need to install the fake-pae package (https://launchpad.net/~prof7bit/+archive /fake-pae) and then replace both vmlinuz and initrd with the versions on the distribution media or reinstall the linux header and image files using a package manager. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/583885 Title: Blank screen on resume with Mobility Radeon 9600 M10 (RV350) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/583885/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
