Hello! I own an aready old VGNZ790DHB, bios R4040M3.
After update to Ubuntu 13.04 I have following issues: * SD card doesn't work (I can see the device in "$lspci") * wifi crashes after reboots: network manager shows "Device is not ready", wifi is absent in "$rfkill list". I can get back to the normal behaviour only after several reboots. (the same problem was since 12.04) * brightness Fn-key don't work Could the source of problems be that "$lsmod |grep sony" doesn't have "sony-laptop"? If I try to add the module: $sudo modprobe sony-laptop $ERROR: could not insert 'sony_laptop': Invalid argument although the module "sony-laptop.ko" is in /lib/modules/3.8.0-17-generic The janitor script could not help to solve issues unlike in previous versions of Ubuntu. Is it worth to try another distribution like Suse instead of solving these problems? all the best, Andrey Sheyko
