Veazer's questions

I am unable to get any output to my external monitor on 12.10. The monitor is recognized and shows the native res (1920x1080, correct) but enabling has no effect. Graphics chipset is Intel Ironlake (Arrandale).

I have tried:

• Full system update after installing
• Oibaf PPA updated drivers (https://launchpad.net/~oibaf/+archive/graphics-drivers)
• Enabling SNA
• Kubuntu 12.10 (in addition to Ubuntu 12.10) Both were fresh installs.

Nothing works, any troubleshooting ideas? Everything is fine on 11.10.

UPDATE 1: Also tried using Intel drivers from Xorg-Edgers PPA (https://launchpad.net/~xorg-edgers/+archive/ppa) Still no output on HDMI.

UPDATE 2: Just tried Lubuntu 12.10, same issue. It appears that any 12.10 downstream distro will likely have this issue.

UPDATE 3: Output from 'xrandr -q'

I'm trying to modify a Firefox plugin in .xpi format using file roller. When I try to resave the file after making modifications, I get an error:

7-Zip [64] 9.20  Copyright (c) 1999-2010 Igor Pavlov  2010-11-18
p7zip Version 9.20 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,4 CPUs)

Scanning

Updating archive /home/user/Desktop/myplugin.xpi

System error:
E_INVALIDARG    

If I try to just save it as a .zip instead, I get this error:

An error occurred while adding files to the archive.

It works fine in maverick and precise, only my oneiric machine is unable to properly save the file. What steps can I take to find the cause of this problem?

After adding the preload package, my applications seem to speed up but if I copy a large file, the file cache grows by more than double the size of the file.

By transferring a single 3-4 GB virtualbox image or video file to an external drive, this huge cache seems to remove all the preloaded applications from memory, leading to increased load times and general performance drops.

Is there a way to copy large, multi-gigabyte files without caching them (i.e. bypassing the file cache)? Or a way to whitelist or blacklist specific folders from being cached?

Every GTK3 theme I've ever tried other than Ambiance or Radiance has some "fallback" buttons when maximized instead of the theme buttons. Is there a fix or a theme without this issue?

Example:

I was happy to find the X Updates PPA as it has made installing newer nVidia drivers much easier. Without using the PPA, I found that the driver installed using the restricted drivers GUI often 'killed' systems with newer nVidia cards. Now it's just a matter of adding the X Updates PPA, updating installed packages then installing the restricted nVidia driver.

Unfortunately it looks like the fglrx-installer in the X-Updates PPA is nearly a year old and I'm a bit leary of using it on newer AMD gear like the Fusion APUs. Is there a repo I can add to easily install those drivers as well? The command line package building is a bit tedious and if there's a PPA that would make the Restricted Driver GUI usable for most ATI & nVidia hardware and it make things much easier.
