heia amy, here is something extra to keep and eye on:
I have been having the same issues. I have a new X201 and trying to get 10.04 up and running.
So far I was able to boot the ubuntu installer via USB stick using the
but I can not get the actual installed instance to boot even with the same parameters. This is both regular and recovery mode.
Anyone know why?
I want to try to install the debs in the launchpad thread but can't do so unless i can boot the system.
Anyway, I sucessfully mounted my installed instanced, chrooted and patched the kernel, compiled and installed it. However updated blew away my grub config (points back to the original install)
I followed the instructions posted here, and was able to get a livecd install from an SD card (using the modeset option ), also edited the /etc/default/grub file and works fine on reboot, also installed later kernels (2.6.34 rc7 etc from mainline) in an attempt to resolve the brightness issue, didn't work.
I see the thinkpad_acpi driver loaded:
lsmod | grep thinkpad
thinkpad_acpi 81537 0
led_class 3455 1 thinkpad_acpi
snd 71802 21 snd_hda_intel,snd_hda_codec,snd_usb_audio,snd_pcm_ oss,snd_mixer_oss,snd_hwdep,snd_usb_lib,snd_pcm,sn d_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_de vice,thinkpad_acpi
nvram 7835 1 thinkpad_acpi
a cat of the thinkpad driver setting:
matt@matt-laptop:~/ibm_driver$ cat /sys/devices/platform/thinkpad_acpi/leds/tpacpi\:\:standby/max_brightness
not sure where to go from here, I did a recompile but since the driver is already enabled (i think) not sure what to do..
I am having similar issues on my lenovo x201 tablet. About one half of the times I boot the machine I get a black screen. The other half of the times everything works out perfectly, even with visual effects like transparency. What could be the reason for this strange behaviour?
I tried the "i915.modeset = 0"-suggestion but this only made things worse: The graphics starts with the wrong resolution and crashes after one second.
Please note that I am completely new to Linux and not so aquainted with the finer details of the booting process and graphics. My system is up to date.
Anyway, I can still work with this problem, I just need to reboot a couple of times in order to get everything running. Still, I would very much like to resolve it.
Any help would be appreciated,

BTW, I'm not sure about the holding in Shift bit... At the grub (bootloader) options screen, I selected Ubuntu, and hit "c" to edit it...then proceeded as you describe.
Although, it seems I had to hold Shift to get the options screen after booting the Ubuntu install CD (10.04, x86-64).
I am having the same problem as LeighB2282. I have ubuntu 10.04 working on my x201 laptop but the external monitor is not detected. If I boot ubuntu without the i915.modeset=0 option then the monitor is detected but not the laptop's screen --its blank. (This is not true however if I connect the external monitor through the docking station, in which case the external monitor is not detected.) In the case that I remove the modeset=0 option, the external monitor is detected but the resolution is off and the gui interface in the system options does not recognize the resolution of the monitor, rather it sticks with the original laptop resolution.
Any help on this would be very much appreciated, as I use this laptop many hours a day and having an external monitor working would help me a lot.
