Frank, please reassign as appropriate: <!-- FIXME --> <!-- bnc#595569, 621469, 673964, 781700 --> <sect2 id="sec.114.kms"> <title>Initializing Graphics with KMS (Kernel Mode Setting)</title> <!-- <para>CHECKIT:12.3</para> --> <para> With openSUSE 11.3 we switched to KMS (Kernel Mode Setting) for Intel, ATI and NVIDIA graphics, which now is our default. If you encounter problems with the KMS driver support (intel, radeon, nouveau), disable KMS by adding <literal>nomodeset</literal> to the kernel boot command line. To set this permanently using Grub 2, the default boot loader, add it to the <literal>GRUB_CMDLINE_LINUX_DEFAULT</literal> kernel default load options line in your <filename>/etc/default/grub</filename> text file as root and running the terminal command </para> <screen>sudo /usr/sbin/grub2-mkconfig --output=/boot/grub2/grub.cfg</screen> <para> for the changes to take effect. Else, for Grub Legacy, add it to the kernel command line in <filename>/boot/grub/menu.lst</filename>, also done as root. This option makes sure the appropriate kernel module (intel, radeon, nouveau) is loaded with <literal>modeset=0</literal> in <filename>initrd</filename>, i.e. KMS is disabled. </para> <para> In the rare cases when loading the DRM module from <filename>initrd</filename> is a general problem and unrelated to KMS, it is even possible to disable loading of the DRM module in <filename>initrd</filename> completely. For this set the <literal>NO_KMS_IN_INITRD</literal> sysconfig variable to <literal>yes</literal> via YaST, which then recreates <filename>initrd</filename> afterwards. Reboot your machine.</para> <para> On Intel without KMS the Xserver falls back to the <literal>fbdev</literal> driver (the <literal>intel</literal> driver only supports KMS); alternatively, for legacy GPUs from Intel the "intellegacy" driver (<systemitem>xorg-x11-driver-video-intel-legacy</systemitem> package) is available, which still supports UMS (User Mode Setting). To use it, edit <filename>/etc/X11/xorg.conf.d/50-device.conf</filename> and change the driver entry to <literal>intellegacy</literal>.</para> <para> On ATI for current GPUs it falls back to <literal>radeonhd</literal>. On NVIDIA without KMS the <literal>nv</literal> driver is used (the <literal>nouveau</literal> driver supports only KMS). Note, newer ATI and NVIDIA GPUs are falling back to <literal>fbdev</literal>, if you specify the <literal>nomodeset</literal> kernel boot parameter.</para> </sect2> ======================================================================= I'll remove it from the Factory release notes soon. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
