I have an Acer Aspire One 725 netbook with AMD C60 (64 bit) dual core 1.333GHz cpu, 2GB DDR, 320GB HDD partitioned 100GB Win7, 220GB open. Trying to boot on live OSDisc flash drive (no CD/DVD drive here) containing Suse12.2 (64 bit). I insert drive and turn on, menu appears offering option to run or install, choose run, boot starts, loads kernel, begins listing actions...at some point text screen skews off and freezes. Only way I can recover is to shut down, unplug flash, reboot. Then comes up in Win7 but without touchpad (which I can turn on with F7). I'm afraid to try the 'install' choice on the menu. Any suggestions?

Probably openSuse has problems with the videochip in that device, check if there is an option to boot in Vesa mode.

Did you turn off secure boot in your bios?

Might be possible to boot this to a different system and use updates or even AMD or (what is it?) fxlgr driver to get video to work. I too suspect video issue.

Thanx all. I don't get a VESA option and boot password is disabled. As to booting a different system I have Suse and Arch Linux on DVD and can't get either to boot - seems to not recognize the device. BIOS says USB-CD but not DVD. Could that be a problem? Also this netbook has Insyde H2O bios and Acer tech support says the Aspire One doesn't support UEFI but the setup menu says H2O has EFI 3.7. Can anyone enlighten me here? Thanx again.

I have an Aspire One 722-0879 with the same BIOS. At present I am running Linux Mint v15 Cinnamon. If I recall I had a similar issue with it locking up when I first tried to run Linux on it. An issue with the wireless network hardware causes it to freeze. The work around for me was to set "Network Boot" as the first priority in the boot order.

So my my BIOS boot order is as follows:
1) Network boot
2) USB HDD
3) USB CDROM
4) HDD0
5) ATAPI CDROM
6) USB FDD

I have installed various Linux distros by using both a USB stick and/or portable USD DVD drive with the above BIOS settings with no problems.

On a side note, the only other issue I encountered with this netbook was substantial CPU/APU lag. By default the video driver is set to "xserver-xorg-video-ati (recommended)". After installing the video driver "fglrx-updates" the lag problem disappeared.

The current free radeon driver does not support setting clockspeed for the GPU in that APU correctly, since the driver lacks dynamic power management. Support for this comes in kernel 3.11 (not by default, setting an option in the bootloader is necessary), I am currently testing that on my discrete GPU and my laptop GPU and it works fine.

What are the hardware specifications of the laptop you are using for a test?

Its an older one with Athlon QL-66 dualcore CPU and Radeon HD3200 GPU (RS780, integrated into the chipset). Power-management is working fine, no need anymore to do that manually, but still a bug present that lets my CPU run about 10°C hotter than with the Catalyst driver. Good enough for me now that I can run Slackware -current again, but hope that this gets fixed.
