Ember crashes with open-source radeon driver

[wesleybruce]

Im using the Fedora add/remove software and thought I got all the worldforge programs but ember wont open and run I get a menu of screen settings and then a blank black screen followed by a return to the desk top and the following message which I had to save to docs.

I can't find instructions on ember or Sear etc that make any sense to me. I'm a recent refugee from microsoft xp. Is there is a possibility that I have missed and installation step on ember, Cyphesis or sear that is causing this? How do I find out where ember is on the hard drive?
Where the heck is ~/.ember/ember.log. ???

Hi, the "~" sign represents your home directory, so in you case the log file should be in /home/wesley_bruce/.ember/ember.log

Version 0.5.4 is however quite an old version. If your version of Fedora doesn't have version 0.5.6 available I would recommend that you instead install the Autopackage version, to be found at http://downloads.sourceforge.net/worldforge/ember-0.5.6.x86.package
Instructions on how to install it can be found at http://www.autopackage.org

ok that did not work. I now have to ember tabs in games and neither
work. The ember seemed to end up in the downloads folder. It did not ask
for a location is it supposed to? I'm a windows refugee so this is a
little daunting.
Also got this:

Summary:

SELinux is preventing ember.bin from
loading /usr/lib/ember/libOgreMain-1.6.2.so
which requires text relocation.

Detailed Description:

The ember.bin application attempted to
load /usr/lib/ember/libOgreMain-1.6.2.so
which requires text relocation. This is a potential security problem.
Most
libraries do not need this permission. Libraries are sometimes coded
incorrectly
and request this permission. The SELinux Memory Protection Tests
(http://people.redhat.com/drepper/selinux-mem.html) web page explains
how to
remove this requirement. You can configure SELinux temporarily to allow
/usr/lib/ember/libOgreMain-1.6.2.so to use relocation as a workaround,
until the
library is fixed. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this
package.

Allowing Access:

If you trust /usr/lib/ember/libOgreMain-1.6.2.so to run correctly, you
can
change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/usr/lib/ember/libOgreMain-1.6.2.so'" You must also change the default
file
context files on the system in order to preserve them even on a full
relabel.
"semanage fcontext -a -t textrel_shlib_t
'/usr/lib/ember/libOgreMain-1.6.2.so'"

Fix Command:

chcon -t textrel_shlib_t '/usr/lib/ember/libOgreMain-1.6.2.so'

Ah, sorry, I forgot that Fedora uses SELinux which places some extra security restrictions on everything. I'll see if Alexey can help you, he's the manager for the Fedora Ember package.

Could tell what graphics card you have and did you install proprietary driver or not?

[wesleybruce (wesleybruce)]

I really don't understand the stuff in the box. lol I hope its a
computer.

RADEON X600 PRO (0x5B62) I may not have the latest driver but found one
at

http://support.amd.com/us/gpudownload/linux/legacy/Pages/radeon_linux.aspx?type=2.4.1&product=2.4.1.3.19&lang=English
I don't know if that's what I should load and install. The installation
instructions is mostly jargon I don't know.
Sorry to be a pest. I'm probably trying to win a drag race with a peddle
car. ;-)

Okay. The default driver in Fedora is free, open-source one. It may have bad performance for 3D graphics.

I'm suggesting you to check how 3D is working for you now in other programs. Check extremetuxracer, for instance.

To install proprietary ATI you will need to setup additional repository that carries stuff that cannot be supplied with main Fedora called RPM Fusion. After that driver will be available in package manager as xorg-x11-drv-fglrx.
But beware that situation with this driver is far-far from perfect. Also it won't support your card in next versions that will be in Fedora-11. So, may be, better to stick with open-source driver for now.
I'll try to investigate what was causing the original crash with it.

It means that SELinux prevents execution for some reason :)
You may temporarily disable SELinux by putting it in permissive mode with GUI config tool in System->Administration->SELinux Management (in Gnome).
There most probably will be another problem, but I'll handle you with it to Erik :)

Not at all. You're very appreciated for bug report.

[wesleybruce (wesleybruce)]

Ok tried extremetuxracer. You guys have a serious penguin fixation. :-D
The graphics works and looks ok. There are problems with the game
controls and it hangs occasionally when I crash the penguin into things.
The music and video continues running but the controls stop working and
even Esc has no effect. However I can't see how the graphics card etc
matters there.
Ati says its moved its linux drivers for my graphic card to 'legacy
drivers' where's that? Is is a place or the junk yard. I could not find
a link marked 'legacy drivers'.

If I need a new graphic card what do you suggest? Are you allowed to
recommend hardware? What fits SELinux, Fedora 10 and will work on fedora
11 and world forge?

How do I create an additional repository is that a folder?

Marking this as invalid since it seems there's nothing that Ember can do to this.
