Common F19 bugs
This page documents common bugs in Fedora 19 and, if available, fixes or workarounds for these problems. If you find your problem in this page, do not file a bug for it, unless otherwise instructed. Where appropriate, a reference to the current bug(s) in Bugzilla is included.
My bug is not listed
Not every bug is listed in this page, but Bugzilla should be a comprehensive database of known bugs. This page is a sampling of the bugs most commonly discussed on our mailing lists and forums.
To see if your bug has already been reported, you can search Bugzilla. If it has not yet been reported, we encourage you to do so to help improve Fedora for yourself and others. A guide to Bugs and feature requests has been prepared to assist you.
If you believe an already-reported bug report should be added to this page because it is commonly encountered, you can:
- Add it yourself, if you have wiki access. Please follow the style and guidelines explained in the comments in the page source.
- Or, add the CommonBugs keyword to the bug report. Someone from the QA team will then inspect the issue to determine whether the bug should be listed as a common bug. To expedite your request, please add a comment to the bug that includes
- a summary of the problem
- any known workarounds
- an assessment on the impact to Fedora users
For reference, you can query Bugzilla for bugs tagged CommonBugs:
- CommonBugs? (bugs with CommonBugs keyword, but do not yet have a link to this page)
- CommonBugs+(bugs with CommonBugs keyword and contain a link to this page)
GDM and GNOME render incorrectly on older systems
Some testing has indicated that Fedora 19's llvmpipe-based software 3D rendering does not work properly on older CPUs (those without SSE2 or equivalent instructions; SSE2 was introduced by Intel with the Pentium 4 in 2001, and AMD added support for it with the introduction of the Opteron and Athlon 64 lines in 2003). If your graphics card is not sufficient for GNOME 3 - which may well be the case on older machines - Fedora will try and use software rendering to display GDM and GNOME, but due to this bug, it may fail entirely or render incorrectly. GNOME 3.8, as included in Fedora 19, no longer has a non-accelerated 'fallback mode' for use on systems where 3D acceleration does not work correctly.
At present the only workaround for this problem is to use a non-3D accelerated login manager and desktop. KDM is probably the most robust alternative login manager. The KDE, Xfce, LXDE and MATE desktops all work without 3D acceleration and would be possible alternatives to GNOME.
