Re: Setting Default Framebuffer Mode
I think it depends on your specific framebuffer driver. It does. I use the rivafb driver on this computer, and it doesn't support kernel arguments at stat-up, so 'vga=whatever' doesn't work with this driver. Instead, you need to edit the fbdev.c file in linux/drivers/video/riva, and change the default settings within struct fb_var_screeninfo rivafb_default_var, to match the settings that you want from /etc/fb.modes. Since I was satisfied with 640x480 but wanted a better refresh rate (from 60 to 100Hz), I had to change pixclock to 22272, left_margin to 48, right_margin to 32, upper_margin to 17, lower_margin to 22, hsync_len to 128, vsync_len to 12. Hopefully this is useful to someone else. Thanks for cluing me on referring to 'documentation' (what's that?!). -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Setting Default Framebuffer Mode
Hello, all Every time my computer starts I need to use fbset to change the resolution. Is there a way to set the default framebuffer mode? Thanks -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

An excerpt from $KERNEL_SOURCE/Documentation/fb/framebuffer.txt: 3. Frame Buffer Resolution Maintenance -- Frame buffer resolutions are maintained using the utility `fbset'. It can change the video mode properties of a frame buffer device. Its main usage is to change the current video mode, e.g. during boot up in one of your /etc/rc.* or /etc/init.d/* files. Fbset uses a video mode database stored in a configuration file, so you can easily add your own modes and refer to them with a simple identifier. -- Seneca [EMAIL PROTECTED] pgp0.pgp Description: PGP signature

Okay, thanks, but when I put it in as a startup file in rcS.d, I get a permission denied error at startup for the fbset command. Is there something more specific I should be doing?
