[SOLVED] Suspend causes reboot on Sony Vaio

I was using a Sony Vaio SR29VN and when I tried to resume from suspension, the laptop would reboot instead of resuming. I understand that this may affect other models, however, I don't have a list.

Luckily it's easy to fix: we need to add acpi_sleep=nonvs kernel option to the grub settings.

Fix

Edit (with root permissions) the line GRUB_CMDLINE_LINUX on the file /etc/default/grub, adding the option acpi_sleep=nonvs.

Fixing Vaio suspend problem

Then run this on the command line:

sudo update-grub2

[FIX] VLC is unable to open the MRL (smb://)

Image
When I tried to open remote video files with VLC via a Samba share I got this error message: Your input can't be opened: VLC is unable to open the MRL 'smb://...' It seems that this problem is related to credentials and can be fixed by entering the credentials for the Samba share in the VLC preferences (Tools > Preferences > Input / Codecs > Access Modules > SMB Input): Note: I only experienced this problem when accessing remote files with PCManFM.
