So, looking at the config file, you neither have VGA_CONSOLE switched on nor L4_FB_DRIVER. So how does your setup look like? I guess that's why you're actually not seeing anything really useful on the screen. So how about enabling VGA_CONSOLE?

I hava enabled the VGA_CONSOLE,and could saw some chang when starting,just like some words's color turned normal,but the keyboard didn't working sitll.Then I enable the L4_FB_DRIVER,but it can't compile right,the error message like this: arch/l4/kernel/main.c:80:5: warning: #warning WARNING: L4FB enabled and also CONFIG_SERIO_I8042 or CONFIG_SERIO_LIBPS2 or CONFIG_VGA_CONSOLE arch/l4/kernel/main.c:81:5: error: #error WARNING: This is usually not wanted. make[1]: *** [arch/l4/kernel/main.o] error 1 make: *** [arch/l4/kernel] error 2 and I used ubuntu-6.06 with gcc version gcc-4.0.3. There seems some problem in my configuration,but I can't solve it. Could you show me with your l4linux config file?

I'm getting lots of weird newlines in L4Linux. Where do they come from and how do I turn them of? Here's a simple example which shows the
problem:
localhost ~ # dd if=/dev/urandom of=/dev/null count=100 100+0 records in 100+0 records out 51200 bytes (51 kB) copied, 0.0262116 s, 2.0 MB/s localhost ~ # dd if=/dev/urandom of=/dev/null count=1000
1000+0 records in 1000+0 records out 512000 bytes (512 kB) copied, 0.274718 s, 1.9 MB/s localhost ~ # dd if=/dev/urandom of=/dev/null count=2000
2000+0 records in 2000+0 records out
1024000 bytes (1.0 MB) copied, 0.580115 s, 1.8 MB/s localhost ~ #
The higher the count value is, the more new lines I get. It's often impossible to see any actual output messages.
I'm occasionally seeing this with slow hosts on Fiasco-UX. What's your setup?

I would really like that you understand what's going on. Let me explain.
Every system we consider here has devices. Those devices are your disk, your keyboard, your monitor, your mouse etc. Each device needs some software which knows this particular device and can drive it, thus it's called a driver. A device can only driven by _exactly_ one driver at a time. This is an important point.
Now, concerning display and key-input, L4Linux and the underlying L4 system can be configured in different ways. - direct access - console use For 'direct access' L4Linux will drive the keyboard and mouse controller and will control the screen (e.g. VGA). And only L4Linux will do that. No one else. For the configuration of L4Linux this means that one needs to enable the keyboard and mouse controller driver and the VGA driver.
For console use, the l4con or DOpE is controlling the keyboard and mouse controller and the screen. And only l4con/DOpE is controlling the keyboard/mouse/screen. No one else. For the configuration of L4Linux this means that L4Linux does not need any keyboard/mouse driver nor any VGA driver. It _just_ needs the l4fb driver (it also does input handling). So this is either or. Never both.
And this is what the above error message wants to say you. You have the l4fb driver enabled (L4_FB_DRIVER) and also the driver for the keyboard/mouse controller and/or the VGA driver. And this does not fit together.
Please consider this when configuring your L4Linux.
Please also consider updating your Ubuntu, gcc-4.0 is ancient nowadays.
