After cloning a hard drive (with Ubuntu 10.04) to a new computer, how can I configure the OS to its new hardware?
What I've done so far:
- Clone desktop HDD to laptop HDD
boot-repairto fix the GRUB setup on laptop HDD
/etc/fstabto list the laptop HDD's UUID
- enter wlan0 as the wireless adapter in the network manager, to get wireless back up.
When I boot, a window pops up saying:
Ubuntu is running in low-graphics mode.
The following error was encountered. You may need to update your configuration to solve this.
(EE) No devices detected.
In the subsequent dialog I choose "Run Ubuntu in low-graphics mode for just one session", and the boot proceeds without any further error messages. However, some problems remain:
- The monitor resolution is wrong; the correct resolution isn't available in the Monitors control panel.
- The headphone jack doesn't seem to work.
Are there some commands I can run which automatically reconfigure the hardware setup, like the Ubuntu installer does?
(You may be wondering why I did this, instead of simply installing Ubuntu on my laptop from a CD, then copying over my desktop's home directory. My workplace desktop uses a particular proxy setup for wired internet connections, which I won't be able to replicate from a fresh Ubuntu install.)
EDIT: I have since gotten the wireless back up; I just had to enter "wlan0" into the network-manager's box for wireless interfaces.
