(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 Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/583885 Title: Blank screen on resume with Mobility Radeon 9600 M10 (RV350) Status in “xserver-xorg-video-ati” package in Ubuntu: Incomplete Bug description: Binary package hint: xorg I just performed a clean install of Ubuntu 10.04 LTS, and I am having difficulties resuming from suspend (S3) state. After suspending (via menu, command line, or closing the lid) my Dell Inspiron 8600 with a ATI Technologies Inc RV350 [Mobility Radeon 9600 M10] video card, waking it results in the screen remaining turned off. The laptop seems to otherwise be resuming properly, and the /var/log/messages seem to indicate my video card resumed "successfully" as well (see messages.resume file to be attached). This occurs regardless of whether radeon.modeset=0 is placed in the boot directives (although, in that case, a cursor is displayed for 1-2 seconds on resume before going to the blank screen). This behavior is constant across using a fresh, updated 10.04, upgrading using the ubuntu-x-swat PPA, and further upgrading using the xorg-edgers PPA (currently installed, and used to collect logs). If there is something else I can try or more information I can provide, please let me know.
