View Full Version : Fedora 27 - laptop - freezes for few seconds after suspend

Acer Aspire Core i7 / 16Gb RAM / 1Tb SSD

I have recently upgraded to 27 from 26 and now encounter a strange problem: after opening the lid and logging in, I have control for about 5 seconds, then the display becomes erratic (title bars disappear from windows and the 'top' bar [name escapes me for the moment] disappears) and I lose control for about 15 seconds. During this time, I know the system is active because I hear the alerts as mail is read; also the disk led stays lit (indicates the disk is thrashing?).

Usually everything comes good at that point, but sometimes it crashes my session and I have to log on again.

None of this was happening under 26, so I am reasonably sure it is not my equipment.

I have not installed any extra software since the upgrade.

Any suggestions would be appreciated, as it is slowly driving me nuts.

Kind regards,
Doug

Thanks for replying, antikythera.


which GUI are you using?Gnome 3.26.2

it is possibly falling over and restarting after resuming from suspend.That would be consistent with what I am observing.

also which file system is root and home formatted to?
Filesystem Size Used Avail Use% Mounted on
devtmpfs 7.8G 0 7.8G 0% /dev
tmpfs 7.8G 25M 7.8G 1% /dev/shm
tmpfs 7.8G 2.1M 7.8G 1% /run
tmpfs 7.8G 0 7.8G 0% /sys/fs/cgroup
/dev/mapper/fedora_womble-root 50G 36G 12G 76% /
tmpfs 7.8G 164K 7.8G 1% /tmp
/dev/sda2 976M 167M 743M 19% /boot
/dev/sda1 200M 11M 189M 6% /boot/efi
/dev/mapper/fedora_womble-home 859G 145G 671G 18% /home
tmpfs 1.6G 16K 1.6G 1% /run/user/42
tmpfs 1.6G 76K 1.6G 1% /run/user/1000

By the way, I still see this behaviour when I suspend/resume with no applications running, just an empty desktop, if that is of any use in diagnosis. I had thought it might have been something like a Java application (JStock) or Virtual Machine Manager not playing well, but that does not seem to be the case.

It turned out to be a Gnome shell extension. I am not certain which one was causing the crash, so I won't mention any names. With all extensions turned off, the computer has returned to stability (famous last words ...).
