Hi All,
I need some help in setting up X11 inside UML - it hangs after the
following set of messages:
~/uml/linux-2.6.18$ ./linux ubd0=debian-3.0r0.ext2 stderr=1
..........................
TCP: Hash tables configured (established 1024 bind 512) TCP reno
registered (Please see attachment "dump.txt" for complete set of
messages.)
This is what I have done until now:
01. Download Linux Kernel 2.6.18 (wget
http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.18.tar.gz)
02. Download the UML patches (wget
http://user-mode-linux.sourceforge.net/work/current/2.6/2.6.18/patches.tar)
03. Apply until x11-fb patch (quilt push x11-fb) 04. Make changes to
x11-fb patch to fix some error
04.01 Fix compilation error => arch/um/drivers/x11_kern.c:397: error:
`soft_cursor' undeclared here (not in a function)
Added the following declaration to the file:x11_kern.c (quilt
edit arch/um/drivers/x11_kern.c):
extern int soft_cursor(struct fb_info *info, struct fb_cursor *cursor);
04.02 Fix to get the option "UML-specific options/Graphics
support/Console display driver support"
Un-comment the following line in file:arch/um/Kconfig (quilt
edit arch/um/Kconfig):
source "drivers/char/Kconfig"
05. Refresh the x11-fb patch (quilt refresh) 06. Apply rest of the
patches (quilt push debug-sysrq-t) 07. Apply patch for PAGE_SHIFT
error (04_include_PAGESHIFT_definition.patch -patch) 08. Configure
defaults for UML (make defconfig ARCH=um) 09. Configure UML (make
menuconfig ARCH=um)
=> Enable "UML-specific options/Graphics support/Support for frame
buffer devices"
=> Disable "UML-specific options/Graphics support/Console display
driver support/VGA text console"
=> Enable "UML-specific options/Graphics support/Console display
driver support/Framebuffer Console support"
=> Enable "UML-specific options/Graphics support/Console display
driver support/Select compiled-in fonts/VGA 8x8 font"
=> Enable "UML-specific options/Graphics support/Console display
driver support/Select compiled-in fonts/VGA 8x16 font"
10. Build UML (make ARCH=um)
Thanks,
~Partha
