Re: Upgrading X220/X230 to FHD 1080p
Thats great for x220 users. I am using an x230 with FHD mod and coreboot. Is your VCC3P commit 840a47e available in the coreboot master?daduke wrote: ↑Mon Apr 29, 2019 11:41 amnew commit - you can now power the nitrocaster PCB from VCC3P instead of VCC, reducing sleep battery drain (see description on the website ^)daduke wrote: ↑Fri Apr 26, 2019 2:42 pmok here it is: https://daduke.org/hardware/x220-fhd/. I couldn't get any coreboot/Seabios display output without the original VGA BIOS, but it's rather easy to extract. Let me know if you have any issues with it
I couldnt find that commit in your fork nor in the master.

Re: Upgrading X220/X230 to FHD 1080p
Just to be sure, does the brightness control work with the Coreboot patch, just as usual?
I read the firmware from my X220, will also mod my X230 when I got all the parts to made that a 13" laptop.
And are the problems with docking stations also solved or do they still need to be taped?

Re: Upgrading X220/X230 to FHD 1080p
Someone posted a kernel patch (workaround) for the display issue (not showing randomly) on Linux.

Amazingly it works with the mentioned commit (Bridging J1 and disconnecting Aux Power). Let's hope for better battery life in suspend.daduke wrote: ↑Thu Jun 06, 2019 11:35 pmI would guess as that's where I got it from: https://review.coreboot.org/c/coreboot/+/28950/
There is no display output of the coreboot prompt (Boot options etc.), only once SeaBIOS is loaded i.e. Linux boot loader.

Re: Upgrading X220/X230 to FHD 1080p
On another note since we are all after 1080p on a 12.1" screen,
Does anyone have a proper way of doing fractional scaling in linux?
So far I've enabled experimental mode in gnome 3.32 on Ubuntu 19.04 giving me a usable (125%) experience in system apps.
However Firefox and others do not render properly (become blurry/fuzzy), which is quite annoying.
Any other solutions out there?

?use this guide to extract the VGA BIOS. Name it vgabios.bin. I could not get any coreboot/Seabios output without this.

I've built and flashed CB with Alexander Couzens' LVDS patch (https://review.coreboot.org/c/coreboot/+/28950/7, without an extracted VBIOS blob (Just CB included VBIOS).
That does not include any code from Sergey (VCC>VCC3P). ( comments patchset 7 https://review.coreboot.org/c/coreboot/+/28950/)
The nitrocaster mod PCB was connected with aux power cable and no J1 bridge.
That gave me display output of CB and Seabios before Kernel was loaded (but higher power usage on sleep and lid closed).
Then I did the aforementioned (disconnect aux and bridge J1). Now there is only display output once the kernel is loaded.
My guess would be that the Mod PCB does not get power until the kernel is loaded. That would mean that I need to implement Sergey's code.
I will report whether that worked for me...

Re: Upgrading X220/X230 to FHD 1080p
I've used the Legacy VGA text mode as the high resolution framebuffer did not play well together with some of the secondary payloads.thrilleratplay wrote: ↑Wed Jun 12, 2019 8:11 amAre you using the Legacy VGA text mode or libgfxinit Linear high-resolution framebuffer?
Both modes worked for Coreboot option screen and subsequent boot into linux kernel.
No VGA BIOS blob necessary.

I've used this guide to assemble the initial CB build with Alexander Couzen's patch. http://wiki.muc.ccc.de/x230modding:start (Mind the current patchlevel 7)
At the current development state there is a merge conflict when rebasing (catching up from patch date to current) with current CB.
That has to be fixed manually in the file (google fix merge conflict git).
Then getting the submodules (3rd party etc.)
After that added Sergey's 3 lines of code to "src/northbridge/intel/sandybridge/gma.c" as described above (around line 557).
Then followed with the rest of the guide (build crosscompiler).
Since I previously had flashed coreboot I flashed the new version internally (no need for raspi flasher).
My working config for this device and mod is here https://pastebin.com/ZXf4fbhq (needs to be saved as .config inside coreboot main directory)
General info on how to build and flash coreboot is here: https://www.coreboot.org/Intel_Sandybri ... d_Tutorial
Needless to say, I strongly advise to backup all data and read out old bios flash images before flashing coreboot.
My build is meant for internal flashing with a flash layout file to only touch the bios region of the flash.

Which 13,3" panel I should use? The B133HAN04.6 or LQ133M1JW21?
Also, does it matter, which bios I'll flash with Nitrocaster rev.6?

Hi,
I'm sorry for posting another reply for troubleshooting a problem, but I didn't manage to find an answer.
My x230 had display with the FHD mod, but after cleaning the fan I don't get any display on the internal screen. Also no backlight visible.
VGA is still working and the board is powered, I also have redone the cables a few times but I'm running out of ideas to troubleshoot this problem.
Can anybody help me please?

Re: Upgrading X220/X230 to FHD 1080p
I've taken my laptop to two places for it to get it done and they can't do it. The one place that almost got it said the board doesn't quite sit on top of the docking area for the solder to make it there. Is directly wiring up the board and taping it down a bad idea? should I try another place? idk where else to take this thing.
also if you're near the pensacola florida area and you have experience with the mod, i'll pay you to get it done.

Re: Upgrading X220/X230 to FHD 1080p
Try to solder the contacts that were soldered. The soldering may have broken when the plugs are disconnected Adapter is better to fix something if my advice helps.Can anybody help me please?
Re: Upgrading X220/X230 to FHD 1080p
To add to this I would recommend to only use solder wick if needed (no vac pump). Also use SMT rated flux.
Nitro caster advises several seconds of heat applied to each pin. This is because of the ROHS compliant lead free solder. It takes much longer to liquify.
When the job is done you should also clean up the slag and flux residue.
Good luck!

Re: Upgrading X220/X230 to FHD 1080p
So...I seem to have made a mistake, and I'm hoping somebody can tell me what it is.
Attempting my second nitrocaster mod, I've wound up with a laptop that the display works, but there's no backlight.
I've tested that the screen itself is good (by plugging it into my other laptop that works), and I've tested that there is backlight power (by plugging back in the original 1366x768 screen)
Does anybody know what would cause this?

Re: Upgrading X220/X230 to FHD 1080p
Did you check the Backlight operation demo: as listed in the very first post on page 1 of this thread?
Check the sense-wire?
Check the new LCD-cable connectors for damage and proper insertion?

Well, continuity seems to check out. Sense wire is always a likely suspect, but wouldn't video be absent too, if that were the issue?

Re: Upgrading X220/X230 to FHD 1080p
Hey Everyone, New to the Forum.
Just finished up soldering the mod into my x230, put everything back together and.... Nothing,
i've checked for shorts with a multi meter, there were none.
when powering on fan spins for 3 seconds then turns back off, any idea what is the issue?,
Here's a photo of the soldering on the board:

Hey guys!
I have the same request Please check my soldering. When I power on the laptop, lcd actually powers on, but it seems like there is no data going to the lcd...
I did everything according to the manual from nitrocaster's store.

Re: Upgrading X220/X230 to FHD 1080p
Just got this installed on my X230 with coreboot. I had to remove/resolder it 2-3 times as i had difficulty with the PTH. I'm currently not getting backlight. Continuity checks out on the sense pin, fuse continuity and voltage to ground (both sides of fuse) is good. Original display works fine. I don't think so, but it might be possible I damaged the capacitor. I'm getting 0.53v when testing the capacitor to ground while the computer is booted. What should I expect here? From what I read this is a PWM pin, but on max brightness I'd expect closer to 3.3v. Any help appreciated.
Re: Upgrading X220/X230 to FHD 1080p
I've checked, rechecked and re-re-rechecked everything on this mod, and I'm just not getting a backlight at all. The sense wire I can confirm is going to ground when the PC is booted. Not sure if it's supposed to be high or low, but considering it's floating when off and to ground when on, I assume it's active low. I am assuming that my problem is either the display, or the cable. Not sure how to confirm it's the display 100% without buying another one... I have a X230 and a X220, but I wanted to see at least one working before I did the 2nd one...
Anyone have any suggestions? Any help appreciated.

Re: Upgrading X220/X230 to FHD 1080p
So if I accidentally removed the C137 capacitor and mayybe bridged two adjacent ones Is it safe to turn on the laptop (to see how it behaves with a dock) or is there a possibility of making more damage by doing that?
