| denixx|h2 | Hi! | 11:40 |
|---|---|---|
| denixx|h2 | I have a Lenovo Miix 320-10ICR | 11:41 |
| denixx|h2 | It have an 8ht gen Intel graphics | 11:41 |
| denixx|h2 | https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units#Eighth_generation | 11:41 |
| denixx|h2 | Actually, Win 10 says it's a Dev 22B0 | 11:42 |
| denixx|h2 | CPU is Atom x5-Z8350 | 11:43 |
| denixx|h2 | So, it's HD Graphics 400 | 11:44 |
| denixx|h2 | I'm trying to get running Bionic in LiveCD mode on it. | 11:45 |
| denixx|h2 | LiveUSB, actually :) | 11:45 |
| denixx|h2 | I've managed "first phase" problems: it's loads, as I can figure out. But it uses only microHDMI output! | 11:46 |
| denixx|h2 | loading it with "nomodeset i915.modeset=1 fbcon=rotate:1" for kernel and "set gfxmode=1200x1980" helps to get rotated screen at first at it's own display. | 11:48 |
| denixx|h2 | But later it gets switched to some other mode and loads graphics, and leaves only microHDMI output enabled. | 11:49 |
| denixx|h2 | Looks like this in final: https://www.dropbox.com/s/60xq3emchvbhbx0/2018-03-04%2012.55.40.jpg?dl=0 | 11:50 |
| denixx|h2 | Disabled main display, and something of Ubuntu Bionic on the other display. | 11:51 |
| denixx|h2 | I am willing to try to disable main display and get desktop just use microHDMI alone. How can I manage it if I even don't know names of video outputs? | 11:52 |
| denixx|h2 | If someone willing to look how it boots, I've shoot a video: https://www.dropbox.com/s/g48pc8ppkjo6rz2/2018-03-04%2012.48.04.mp4?dl=0 | 11:55 |
| denixx|h2 | If someone can guide me to some page where I can find information about video names, I'd be happy :) | 12:07 |
| denixx|h2 | Hmmm. What if I'll try to press ctrl+alt+f2 at final stage... bbs... | 12:24 |
| denixx|h2 | Looks like https://bugs.freedesktop.org/show_bug.cgi?id=96571 | 13:05 |
| ubottu | Freedesktop bug 96571 in DRM/Intel "[CHV] Backlight init fails on Surface 3 if module load order is wrong" [Minor,New] | 13:05 |
| denixx|h2 | "[drm:pwm_setup_backlight [i915]] *ERROR* Failed to own the pwm chip" | 13:06 |
| denixx|h2 | Heh, looks like I need to make custom kernel. | 13:22 |
| TJ- | denixx|h2: or just create a rule in /etc/modprobe.d/ to control load-order using the 'install' directive | 13:26 |
| denixx|h2 | TJ-: can I do it for LiveUSB? | 13:27 |
| TJ- | denixx|h2: Hmmm, there are kernel command-line options that can control some parts of modprobe, let me check | 13:27 |
| denixx|h2 | I managed to get to desktop with "video=DSP-1:d" :) | 13:28 |
| denixx|h2 | Sorry | 13:29 |
| denixx|h2 | "video=DSI-1:d" | 13:29 |
| denixx|h2 | https://www.dropbox.com/s/lv6njy5gw9ghnq1/2018-03-04%2015.28.00.jpg?dl=0 | 13:29 |

| denixx|h2 | But if I could manage the order for i915 to make it boot after backlight control be available, I may make this as solution somewhere :) | 13:31 |
| TJ- | no, kernel command-line doesn't have the option - although I was reading kernel docs/code yesterday where I am /sure/ I saw a bunch of module.xxxx options for doing just this! | 13:33 |
| denixx|h2 | I think I will be overwhelmed with all that if I start to dig just now. :) | 13:35 |
| denixx|h2 | May I ask additional question: | 13:37 |
| denixx|h2 | Can that be fixed after installation? | 13:37 |
| denixx|h2 | Or kernel build options is the only workaround? | 13:37 |
| denixx|h2 | Never messed with it :) Can try to, though... | 13:38 |
| denixx|h2 | [15:26:14] <TJ-> denixx|h2: or just create a rule in /etc/modprobe.d/ to control load-order using the 'install' directive | 13:47 |
| denixx|h2 | TJ-: Kan you throw me some readme link? | 13:47 |
| denixx|h2 | Can* | 13:47 |
| TJ- | denixx|h2: 'man modprobe.d' lists the syntax, I can't find an example now of using 'install' to control load order but I've done it many years ago; it basically strings multiple 'install' commands together so you do something like "install i915 modprobe <first-module-name>" | 13:56 |
| denixx|h2 | TJ-: Thanks a lot! | 15:09 |
| denixx|h2 | I'll check later. | 15:09 |
