14.04 LTS issues with Intel HD 4400 Haswell

[digitaljedi2]

I have tried for a couple of weeks now to find a solution to this and I'm still not finding one so I am posting here.

I have a Dell 17r Laptop with the Intel HD 4400 Haswell graphics built into the processor (i7). When I installed Ubuntu I had to set 'nomodeset' in the kernel or I would get low graphics mode. It boots fine, it looks fine now. The problem is that when I check the details I see that it is showing Galium as the Graphics driver. I get a little bit of tearing at times and I can't adjust the brightness. I tried creating the 20-intel.conf file in xorg.d to get the brightness control working and I've had no luck with that. I'm pretty sure that won't work until I force the machine to use the Intel graphics driver because right now it only shows Dell backlight and no Intel backlight. I haven't been able to figure out how to make that happen nor have I found any posts online that help either. Does anyone have any suggestions?

I think you should just be using the Intel open source i915 driver.

There is a large thread on 17r, but it may not be one of these?

Thanks. The first link seemed more focused on dual booting and HD issues, but I think there will be some helpful info in the other 2. I'll give it all a go when I get home. I tried a couple of proposed backlight fixes with no result, but I saw more more info in one of those links. One of the issues that through me for a loop, if I recall correctly, was that I didn't find a xorg.conf in 14.04, but instead found xorg.conf.d full of individual config files. I've been in Arch land for a while and when I came back to Ubuntu either things had changed or I just didn't remember how to do things. That was the only hope I felt I had for forcing the use of the Intel graphics driver. Now maybe I have some other possibilities.

Thanks again. I'll report back my results.

The first link was all hard drive info. The 2nd would probably help more if my machine was detecting intel backlight, but it only shows dell backlight at the moment. The 3rd link unfortunately didn't help either.

I did a little more research and saw a post somewhere that said the newer kernels will likely fix the issue. I added the pre-release repos and did an apt-get update and saw a newer kernel was available that way, but so were a ton of other updates. I wasn't sure if using pre-release repos made for a very stable system and I'm needing this to remain stable as I'm using this laptop for development work. At least for the time being it looks alright, I just can't adjust the brightness and I get some tearing. My understanding of the situation is that the new Intel graphics drivers are a part of Ubuntu 14.04 already so I feel like I just need to force them to be used somehow instead of Gallium.

Any other suggestions would be greatly appreciated.

The last couple of posts in third link discuss adding a ppa to add a newer kernel than the one Ubuntu has as standard for 14.04.
Ubuntu probably will not have that kernel or maybe the next one, in the next point release of 14.04 or 14.10.

Also mentions newer kernel.

After reading your links, the newer kernel is sounding more and more to me like the fix. Rather than using pre-release repos, I'll use that ppa for 3.15-RC2 and see if that gets me going. I have a good feeling about this one!

I'll report my results tonight.

Oh yeah, and thanks a million for the help thus far!

Are you still booting with nomodeset?

Please give /var/log/Xorg.0.log (use code tags).

Still using nomodeset. Will post logs when I get home.

You should only get the updates you want out of the proposed/pre-release repo (and then disable it). You can install the kernel, and if something goes wrong, just boot into the old one and remove the pre-release kernel.

My understanding of the situation is that the new Intel graphics drivers are a part of Ubuntu 14.04 already so I feel like I just need to force them to be used somehow instead of Gallium..

I think you have it backwards. You probably need to get kernel modesetting (i.e. boot without nomodeset) working and then the 3D drivers will take care of themselves

There's the log. Trying a few things. Will post back.

EDIT: Just removed 'nomodeset' from etc/default/grub. To my surprise it actually booted correctly, but still no Intel driver or birghtness control.
:AND AGAIN: Tried the kernel from the pre-release (kernel, headers, firmware packages). Installed usccessfully, no Intel driver yet.
