<pre>I tried a delayed switch while the window manager is active:
echo DDIS > /sys/kernel/debug/vgaswitcheroo/switch
result:
[ 143.760681] vga_switcheroo: client 1 refused switch
[ 143.760687] vga_switcheroo: setting delayed switch to client 1
Afterwards I restart the window manager (logout, login)
result:
[ 165.888245] vga_switcheroo: processing delayed switch to 1
[ 165.888254] vga_switcheroo: client 1 refused switch
[ 165.912704] vga_switcheroo: processing delayed switch to 1
[ 165.912708] vga_switcheroo: client 101 refused switch
[ 166.955699] vga_switcheroo: processing delayed switch to 1
[ 166.955706] vga_switcheroo: client 0 refused switch
[ 166.955728] vga_switcheroo: processing delayed switch to 1
[ 166.955730] vga_switcheroo: client 0 refused switch
[ 166.956444] vga_switcheroo: processing delayed switch to 1
[ 166.956449] vga_switcheroo: client 0 refused switch
Are there any further steps I should do besides restarting the window manager?
I thought restarting the wm is sufficient.
Do you think the PRIME feature may keep the device nodes open?</pre>
