My Debian sid test was with the open source drivers and resulted in the same problem with suspend.
However, there has been a recent BIOS update (version A02 -> A05) released by DELL. Since the update, it seems that the suspend problem just went away, both on Ubuntu LTS and Debian Sid. Can't say for sure that this is due to the BIOS update (no detailed changelog available), but the timeline points to it. 2014-03-16 17:48 GMT+00:00 Pali <[email protected]>: > Maybe there is problem with fglrx blob.
