@Trevino,
Can I have your prepatch source kernel package? Your compiled kernel is working for my Acer 4745G except for my wireless card ( Network controller: Broadcom Corporation Device 4357) and for my virtualbox (the vboxdrv module is not there) ..
thanks
ari97 thanks for your diligence , but would you mind explaining your procedures and steps for others coming to this thread?
Dear All,
Just wanted to post success using Trevino's (Mille Grazie !) provided packages. I'm running an Aspire 4820T-434G32Mn. This model has no ATI graphics card. WiFi works immediately now (no need to right-click on Network Manager and enable it) and connects to the preferred network after login.
Everything related to the battery recognition seems to work fine, however: I can't seem to get those reputed 8 hours of battery life out of it, more like 3-4. I will gather more empirical data as the days and weeks go on, but was wondering if other users can post their battery life and/or confirm mine.
My usage is certainly not 'heavy', just normal web browsing, and some application usage. No kernel compilations or anything like that, so battery life should really be in excess of 3 hours.
Looking forward to your feedback.

@enno: Yes, I can confirm the drop in battery life when running on ubuntu. I have the 5820TG and it consumes more battery due to the larger display and I am looking at somewhere between 2-3 hours. However, Trevino has posted a script on http://forum.ubuntu-it.org/index.php...tml#msg3101266 . Perhaps you can make sense out of it cos I can't. I want to get my battery up and running to maximum performance too. Also, is your optical drive working fine? I can't seem to eject nor detect it under ubuntu.
@lyradmil
That is the one thing not working right now, I can't eject the drive using the button. I have to type 'eject' in the shell to get it working.
I am fairly sure that we're seeing more of the same old Windows-centric manufacturer policy that brings us things like corrupt battery status code and other 'hacked' hardware-OS interaction - things you don't notice when using the default Windows 7 install. For what it's worth, I will send an email to Acer asking them to re-think their policy and supply the customers with more user-friendly hardware.
I am sure it will not amount to much - besides an automated response. But, in the words of Gandhi: "You must be the change you want to see in the world !"
@enno: That's strange ***. I tried doing that in the shell but it ain't working for me either. Bummer. I'm more concerned about the battery life in any case. That's what we got the TimelineX for!
Anyone?
Hi
I have a Acer 4820TG, BIOS 1.15 and I´m using kernel 2.6.34-aspire-4820tg. But I have a problem with vga_switcheroo. It looks like something is wrong with Radeon card. There is a part from dmesg:

Anyone know what is wrong? Thanks for help.
