Recently I installed Ubuntu 17.10 on my ThinkPad T530.But I have a problem (and I know how much ThinkPad hardware is supported on the linux world).So If I close the lid,the thing won't get on sleep mode.I'm worried because it might be a hardware problem.So my questions are:
1.Did somebody tested Ubuntu on a T530/T430 and does the auto sleep when close the lid?
2.How can I fix it? I already tried to change /etc/systemd/logind.conf
Any help is appreciated Thanks
