Re: [lfs-support] Blank screen when booting with 3.13.3 kernel. - LFS 7.5
I've built LFS 7.5 with the 3.13.3 kernel but receive a blank screen upon booting. As an experiment, I unselected AGP Support in my kernel configuration and can successfully boot. My thinking was perhaps there's a problem with AGP support. However, as I'm running LFS/BLFS 7.4, I compiled that 3.10.10 kernel in my LFS 7.5 build and CAN successfully with with AGP support. I compiled the kernel with the same .config I used when compiling the LFS 7.5 3.13.3 kernel. I also received a blank screen with the 3.13.5 kernel, so the problem isn't unique to 3.13.3. It appears there's a problem with newer kernels. However, I certainly can't ignore the possibility of user error, as that's my talent. A few questions: Does it make sense it's a kernel version problem? If not, what might I have done wrong? Will there be problems running an older kernel (3.10.10) than the kernel with which I built LFS 7.5 (3.13.3)? My box is a Sony Vaio VGN-N220E. I soldiered on with the 3.10.10 kernel and was surprised I could compile xorg with BLFS 7.5. However, I still couldn't boot with a newer kernel but can boot and bring up X with the old. As I can apparently continue with my 3.10.10 kernel without incident methinks I'll run with that until the next LFS/BLFS release. I'm still surprised I could compile LFS 7.5 with the 3.13.3 kernel and then revert to an older kernel with BLFS 7.5. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

The trick was that backlight was set to zero. Pressing Brightness Up key brought up the display.

(you can get it from chroot after reboot iirc). Compress it before sending or it might get blocked. I also had no success after deselecting Sony Vaio Programmable I/O Control Device Support. A couple of things I noticed, the first of which is relevant to this, and hte second of which might make things more comfortable when you have this issue sorted. First: Mar 12 13:22:40 lfs kernel: [Firmware Bug]: ACPI: No _BQC method, cannot determine initial brightness Mar 12 13:22:40 lfs kernel: [Firmware Bug]: ACPI: No _BQC method, cannot determine initial brightness This is supposedly fixed with acpi_backlight=vendor but I think you said that didn't help. Later, some messages showing the console was created : Mar 12 13:22:40 lfs kernel: fbcon: inteldrmfb (fb0) is primary device Mar 12 13:22:40 lfs kernel: Console: switching to colour frame buffer device 160x50 Mar 12 13:22:40 lfs kernel: i915 :00:02.0: fb0: inteldrmfb frame buffer device So it seems that the console is there, but without the backlight. Does your config have all of the CONFIG_BACKLIGHT settings which you had in 3.10 ? Looking at one of the _many_ matches for ACPI: No _BQC method I found an old one which led me to suggest that you try i915.invert_brightness=1 in the boot args. If that helps, you might need to take it upstream : there seem to be a horrendous number of variations in intel graphics chips/implementations, and breakage of some models seems to happen from time to time. This option is documented in the kernel's Documentation/kernel-parameters.txt file. I assume that you are putting the options in the right place, on the same line as root= ? I'm sure you are, but best to check. Iff none of this helps, it might be a kernel regression. Ideally, try to isolate where it happened (e.g. try 3.13.0, 3.12.0, 3.11.0 until you find one that works, and then perhaps move forward through its stable releases to find out where it broke). It's also possible that this has worked sometimes, but not others, on your hardware. *** But first try the latest 3.13 just in case it has already been fixed *** Second: I don't know what size of screen you have (inches or cm, as well as pixels), but 160x50 might be a bit tiny to read - if so, after you can get a display, change (or add) video=x in the boot args where is the number of horizontal pixels on your screen, and is the vertical. On my old 1600x1200 4:3 screen I can also pass 1024x768 or 800x600, but I don't know what your screen size is, or if there are any conventional smaller sizes which would fit onto it. If you are trying this, copying the grub stanza for the kernel but with something different in the menuentry such as your x and just adding the video= will let you see it it helps and still be able to go back to the first one. Using a bigger consolefont can also help - on my netbook I use a 12x22 font to make it easier to read. That requires setting font support, fonts, and Sun 12x22 in the kernel, and the LFS sysconfig will need to either _not_ specify a font (i.e. use the kernel's sun font which is ok for American), or use one of the 12x22 fonts from kbd to get wider coverage. NB specifying a 12x22 font in LFS on the current kernel which probably doesn't support 12x22 will not load the 12x22. If you want to try 12x22, then I suggest you try it in the kernel and look at the kernel messages before userspace drops back to whatever font you are currently using. Then you can decide is 12x22 is useful for you, and either continue, and change the font in LFS, or give it up as too big. ĸen -- das eine Mal als Tragödie, dieses Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
