עדכון: הפעלת beryl על knoppix

[Nihility]

לכל אלו שהיו להם בעיות להפעיל את בריל על קנופיקס עם כרטיסי מסך חדשים של נוידיה,

הנה הדרך לגרום לזה לעבוד.

אגב, ממש בקרוב תצא גרסת 5.2.1!

To all of you, first you need to make sure that your graphics card has

Nvidia acceleration.

For this it is neccessary to use apt-get or synaptic and install

nvidia-glx

nvidia-kernel-common

nvidia-kernel-2.6.18-4 (kernel sources)

OR the kernel sources for kernel 2.6.19 . Knoppix 5.1.1uses kernel 2.6.19 by default and if like me your CD or DVD was a cover disk then you may not have the kernel sources. This is why I used apt-get to install kernel 2.6.18-4.

After installing the packages check that Nvidia acceleration is enabled. You should see a Green and white Nvidia splash screen, log out of kde and restart the xserver, ctrl-alt-backspace

If no splash screen appears then the your /etc/X11/xorg.conf file may need modifying.

This is especially true in your case joeylutledge. In the section "Device"

Section "Device"

### Available Driver options are:-

# sw_cursor is needed for some ati and radeon cards

--snip--

Identifier "Card0"

# auto-generated by KNOPPIX mkxorgconfig

Driver "nv"

VendorName "All"

Change the line that starts Driver from nv to nvidia as below:

Driver "nvidia"

You should now see an Nvidia spash screen when starting kdm. If this works then from a terminal type glxinfo. This will generate lots of output

including whether your card has the glx extensions. Sample below:

anc@orac:~$ glxinfo

name of display: :0.0

display: :0 screen: 0

direct rendering: Yes

server glx vendor string: NVIDIA Corporation

server glx version string: 1.4

server glx extensions:

GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig,

GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control,

GLX_ARB_multisample, GLX_NV_float_buffer

client glx vendor string: NVIDIA Corporation

client glx version string: 1.4

client glx extensions:

GLX_ARB_get_proc_address, GLX_ARB_multisample, GLX_EXT_visual_info,

GLX_EXT_visual_rating, GLX_EXT_import_context, GLX_SGI_video_sync,

GLX_NV_swap_group, GLX_NV_video_out, GLX_SGIX_fbconfig, GLX_SGIX_pbuffer,

GLX_SGI_swap_control, GLX_NV_float_buffer, GLX_ARB_fbconfig_float

GLX version: 1.3

GLX extensions:

GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig,

GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control,

GLX_ARB_multisample, GLX_NV_float_buffer, GLX_ARB_get_proc_address

--snip--

Now for the last part, open a terminal and type

beryl-mangager

You should see a splashscreen followed by a diamond in the kde tray. If so, try switching to desktop 2 or 3 the screen will rotate. Hold down ctrl and alt and

grab the top left corner of the screen, you should be able to roate and spin your desktop cube.

If something fails:

Try and restart the x-server by pressing ctrl-alt-backspace

If you have a garbled display, look closely you may find part of an error message that is readable.

Check dmesg and /var/log/Xorg.0.log for clues.

In my case my Sparkle Nvidia GeForce 5700 Ultra card did not support GLX textures at the default colour depth which was 16 bit. I changed this

to 24 bit in my xorg.conf file and it worked.

Good luck.
