--------------------------------------------
Summary: Cannot connect to older ubuntu versions when glyph cache
is disabled
Key: GUACAMOLE-1369
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1369
Project: Guacamole
Issue Type: Bug
Components: guacamole
Affects Versions: 1.3.0
Reporter: Dominik Borkowski
Hello,
Per recommendations from a previous report about disconnects in Windows 7, we
disabled glyph cache. Unfortunately, while it fixed windows, it broke some of
the older Linux clients (Ubuntu 14.04 & 16.04). Guacamole 1.3.0 fails to
connect to xrdp service on those systems with `disable-glyph-caching` set to
true.
Looking at the debug logs we see:
```

```
Is there any other option we should try to address these clients? While we have
hundreds of discrete sessions, our setup relies on a single set of options, so
ideally we'd need to identify a set that works for all clients. As a reference,
guacamole 1.2.0 works fine with both new and old Linux and Windows versions.
Thank you!
