SUMMARY If I am at home, I can nfs mount a directory with scanned documents from my nas. fstab entry: nas.local:/volume1/shared /home/arved/nas/shared nfs rw,relatime,noauto,x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0 If I am not at home, of course this volume is not mounted, as nas.local does not resolve. Unfortunately upon opening okular it tries to open the recently opened documents. It fails to open the documents that don't exists and retries before finally giving up and showing the UI. STEPS TO REPRODUCE 1. NFS mount directory and open foo.pdf from this directory. 2. Shut down your laptop move somewhere else where the nfs mount does not resolve. 3. type "okular bar.pdf " in a local directory. OBSERVED RESULT No GUI is shown for 30 seconds. strace output reveals what okular is trying to do: access("/home/arved/nas/shared/scanner/E79221D1X112433_01012019_000313_000282.pdf", F_OK) = -1 ENODEV (No such device) access("/home/arved/nas/shared/scanner/E79221D1X112433_01052019_213837_000293.pdf", F_OK) = -1 ENODEV (No such device) It tries to open every file twice. At least this could be speed up by trying only once, because it is unlikely the file becomes available a few seconds after first attempt fails. EXPECTED RESULT okular opens instantly. If the old files really need to be read, this could be done in a background thread after the UI is shown to the user. Or a dialog could be shown "Trying to open last opened files" etc. The end-user should need to run strace to figure out why okular takes such a long time to start.
