Kernel 2.6.17.13 build display problem

I have just built my first kernel from the 2.6.17.13 sources and it all seems to work (apart from a few problems with ALSA and stuff). However there is a strange problem with my display. At boot time I now get a large logo (10.2 gave me a small one) and my screen appears in 25 line mode. I have tried putting "vga=ask" into lilo and selected different modes with no apparent difference to the screen, X works OK though. Have I set something wrong in my compilation ? If so do I have to go through the whole process again (it took about 5 hours last time - I have a slow machine ) or can I just recompile the offending module and relink the object filesd to an image ? I have not cleared out any object files from my previous compilation.

Thanks for your time..

There is a setting in .config that selects the startup resolution. I just saw it but can't remember the details. make menuconfig or make xconfig will let you seek the necessary change. The appropriate xxx.o file can then be deleted and it will be the only recompilation that will be done by make as it rebuilds the kernel.

Under Graphics support > Logo configuration > Bootup logo
you need Standard 224-color Linux logo (LOGO_LINUX_CLUT224).

Code:

mingdao@silas:~$ cat kernel/linux-2.6.17.13/.config | grep -i logo

# Logo configuration

CONFIG_LOGO=y

# CONFIG_LOGO_LINUX_MONO is not set

# CONFIG_LOGO_LINUX_VGA16 is not set

CONFIG_LOGO_LINUX_CLUT224=y

Not sure about your other issue. For Framebuffer font I use:

Code:

mingdao@silas:~$ cat kernel/linux-2.6.17.13/.config | grep -i font

CONFIG_FONTS=y

# CONFIG_FONT_8x8 is not set

CONFIG_FONT_8x16=y

Quote:

VGA 8x16 font (FONT_8x16)

This is the "high resolution" font for the VGA frame buffer (the one
provided by the VGA text console 80x25 mode.

And 80x25 looks much smaller and nicer than 80x50.

You might have an incorrect framebuffer support. What works
well for me is CONFIG_FB_VESA=y. Maybe these options:

Code:

CONFIG_FB=y

CONFIG_FB_FIRMWARE_EDID=y

CONFIG_FB_VESA=y

CONFIG_FRAMEBUFFER_CONSOLE=y

CONFIG_FONTS=y

CONFIG_FONT_8x16=y

will serve you well.
