I’ve just upgraded to Rocky Linux 9. When using Rocky Linux 8, I used KDE from EPEL, but since KDE has no usable scanner applications (Skanlite allows single-page scans only, and Skanpage is missing in EPEL), I resorted to Simple Scan (a GNOME application).
Now I tried to use Simple Scan with KDE from EPEL under Rocky Linux 9, but I think there might be some missing dependency somewhere.
During a scan, the window borders flicker weirdly, and after the second scanning attempt the application downright crashed.
I tried to start Simple Scan from the command line, and I got loads of errors like these:
(simple-scan:14827): Gtk-WARNING **: 16:36:05.660: drawing failure for widget
'GtkDrawingArea': invalid value (typically too big) for the size of the input
(surface, pattern, etc.)
Maybe some GNOME dependency missing under the hood ?
Again, I just found the solution. The packaged simple-scan application is manifestly buggy. So I removed it and replaced it with the corresponding Flatpak, which works perfectly and also integrates nicely into KDE.
It may be worth noting here that the version of Gimp that comes with el9 isn’t compatible with the xsane plugin (as far as I’ve been able to determine at a quick look) so you can’t import scanned items direclty into Gimp like you could with el8 (and earlier).
Haha, now I’m curious. I know the interface isn’t up to much, but it’s functional. It’s about the only scanning app I’ve ever used on Linux.
That said, I may just get a printer with a scanner built in that can send it over email or to a network share with samba/nfs. Then I’ll never need to connect over USB to scan.
