<p dir="ltr">Hi</p>
<p dir="ltr">Firstly you should open a bug on bugzilla and provide all relevant information there like a copy of your dmesg and Xorg.0.log output of lspci -nn</p>
<p dir="ltr">You should also state what versions of various packages you're using if you're and what you've tried changing</p>
<p dir="ltr">Also try the latest rc kernel to see if that fixes your issue</p>
<p dir="ltr">Are you using any kernel overrides like fbc, rc7 or forcing atomic? If so switch them off - if you don't know what they are then don't worry</p>
<p dir="ltr">Cheers</p>
<p dir="ltr">Mike</p>
