MacBookAir4,1 & MacBookAir4,2 (MBA 2011) support

[hueythecat]

What are the chances- I finally transition to my mba this morning and the kernal update screws my resolution(mba 4,1).

Running the fix-i915.sh presently

How do you boot back to 3.0.0-12 - its not in the grub menu?

My resolution is poked even after running post-install on 3.0.0-13

Ok

I'm beyond my depth here - but I noticed the the problem was the patch not applying to the intel_bios.c

I manually pasted over (based on you panel model)

panel_fixed_mode->hdisplay = 1366;
+ panel_fixed_mode->hsync_start = 1398;
+ panel_fixed_mode->hsync_end = 1566;
+ panel_fixed_mode->htotal = 1734;
+ panel_fixed_mode->vdisplay = 768;
+ panel_fixed_mode->vsync_start = 772;
+ panel_fixed_mode->vsync_end = 776;
+ panel_fixed_mode->vtotal = 792;
+ panel_fixed_mode->clock = 72500;
+ panel_fixed_mode->type = 0x48;
+ panel_fixed_mode->flags = 0xa;
+ drm_mode_set_name(panel_fixed_mode);
drm_mode_debug_printmodeline(panel_fixed_mode);

(but not this) temp_mode = kzalloc(sizeof(*temp_mode), GFP_KERNEL);
It gave me an error and was specified already in the file

then followed the rest of the shell script - running native res on my mba4,1 linux kernel 3.0.0.13 now.

Some strange things happening though:

My dash overlay is launching windowed not full screen & my alt-tab gui is basic(small icons) not fancy gui.

@Murphy2712: sounds weird. i had something happen in gnome2d. I would recommend installing CompizConfigSettings and try setting whichever window-switcher you prefer to use alt-tab. Btw try super-tab as well since that's often set to be an alternate window-switcher. This can also be used to configure switching desktop (and all other) shortcuts.

You're right, super-tab works!
I think the keyboard layout is wrong, I have other issues with keys and unity-3d:
- changing the keyboard backlight doesn't work,
- volume keys are shifted (mute=F9, vol down=F10, vol up=F11, eject(!??)=F11),
- super does not open the left bar.

I noticed another minor problem: when using the usb-to-ethernet cable, after sleep/resume, it does not connect to network, I need to unplug/replug.


Today I updated some packages and had no login screen when rebooting.
=> I needed "nomodeset".
I've run post-install-oneiric.sh but it didn't help.
Then I downloaded and run "sudo ./fix-i915.sh" and now it works again (with full resolution)

@hueythecat I recall the grub menu has an item names something like "previous linux" which will list the older kernels.

BTW, the ambient temperature is 73 F (23 C) and as you can see, the proximity temp is 38 C. Under Ubuntu, I can barely get under 50 C and that's with the rc=6 kernel boot option, which would support the evidence gathered from XBattery that OS X is using less power.

On Linux the proximity temperature is on applesmc-isa-0300/TC0P, I am getting approximately the same results on OS X than on Ubuntu (using unity2D). My proximity temp is around 39ºC to 42ºC when the laptop is idle:

The post-install sets-up my preferences (which are more PC-like).

...You can comment out the natural scrolling if you don't like it.

...Feel free to comment out the code which sets the shift-special settings.

Hey all, I've been using the MBA 4-2 for a while without issue (after I followed the instructions on the wiki). But yesterday when I updated, the display appears to have shifted and now overlapping on the bottom and right sides. Everything is still usable, but is there any way to expand the display back to the full screen size?

Here's a picture. Notice how the right and bottom edges of the display end early, then restart the display.

No strange things - Unity had launched in 2d not 3d - all good in 3d

@huey: so just to be sure. After updating you just reran fix_i915 but without the line:

  temp_mode = kzalloc(sizeof(*temp_mode), GFP_KERNEL);

And you have everything back up and running like normal?
