Description Bill Gianopoulos 2016-03-31 22:43:30 UTC
I have 2 systems with AMD/ATI graphics that hang trying to start the Xserver after  a graphical login.  I also have 1 system with AMD.ATI graphics cards that seems to work just fine.  I will post the output from lshw on all three systems.

Comment 4 Bill Gianopoulos 2016-03-31 22:55:35 UTC
Reverting to kernel version 4.4.6-300.fc23.x86_64 avoids the issue.

Comment 5 Bill Gianopoulos 2016-03-31 23:05:11 UTC
Obviously, I could have just as easily filed this under the xorg ATI driver.  Feel free to change the component if you determine that is the right thing to do.

Comment 6 Bill Gianopoulos 2016-04-04 16:54:36 UTC
IT appears this has nothing to do with the xorg ati driver as that does not even seem to come into play anymore.

Comment 7 Bill Gianopoulos 2016-04-04 16:58:25 UTC
The issue is identical if I completely uninstall the xorg-x11-drv-ati package.  Everything still works with the 4.4.6 kernel and fails with the current fedora 24 kernel.

Comment 8 Bill Gianopoulos 2016-04-04 17:15:50 UTC
Hmm seems I was wrong there.  it looked just as hung, and although the behavior is still bad without the xorg ati driver and it seems to take forever fr anything to happen it is really  not the same hang.  But still no problems with or without this driver installed with the older kernel so I have no idea what that means.

Comment 9 Bill Gianopoulos 2016-06-10 21:10:26 UTC
Not sure what fixed it, but current fedora24 builds work correctly on both of the laptops which previously exhibited this issue.

Comment 10 Justin M. Forbes 2016-06-13 17:09:06 UTC
Glad to hear it, there were a few fixes in the recent stable updates that likely took care of it.
