Gnome hang and Plasma white page .

Hi ,

Yesterday i wanted to remove Gnome and install Plasma 5 . so the following events happened :

1-installed Catalyst driver for my machine with yaourt catalyst-test .
2- removed gnome and gdm .
3- installed plasma and sddm
4- enabled sddm .

Now first problem happened :
white page i just see the cursor . i can move it but nothing other than the white page is displayed there .

5- So i decided to move back to gnome  . After installing it i got another problem :

Now when i boot Arch  . the device is stuck at :
starting user manager UID 120
removing user manager .
Starting user manager .

thanks in advance .

Re: Gnome hang and Plasma white page .

exactly the same problem here, I think the problem is result from catalyst whitout latest opengl(which qt5 depends on) supported.
When I attemp to run qtcreator, I only get a white page too.But it provides some informaition like:

QOpenGLShaderProgram::uniformLocation( qt_Matrix ): shader program is not linked
QOpenGLShaderProgram: could not create shader program
QOpenGLShader: could not create shader
QOpenGLShader: could not create shader
shader compilation failed: 
""
QOpenGLShaderProgram::uniformLocation( matrix ): shader program is not linked
QOpenGLShaderProgram::uniformLocation( color ): shader program is not linked
QOpenGLShaderProgram::uniformLocation( textureScale ): shader program is not linked
QOpenGLShaderProgram::uniformLocation( dpr ): shader program is not linked
QOpenGLShaderProgram: could not create shader program
QOpenGLShader: could not create shader
QOpenGLShader: could not create shader
shader compilation failed: 

here is a post about the sddm and comments provide a method to solve the problem by disabling SElinux.But it's not working for me .Because I don't install SElinux.

holp the information was helpful.
