Talk:Installing Ubuntu 7.10 (Gutsy Gibbon) on a ThinkPad T61
Core 2 Duo running at 800 mHz?
The applications Sysinfo and PowerTOP both say that my CPU is running at 800 MHz. When I first open Sysinfo, it says a number around 2 GHz but it then drops to 800 MHz. Sysinfo says something about laptop CPU frequency changing (being "dynamic"), but it remains static at 800 MHz. SteveSims 00:51, 13 September 2007 (UTC)
This is normal. This is the "frequency scaling" feature of the laptop. Whenever the processors aren't being used they drop down to 800MHz to conserve power. All you have to do is run some CPU-intensive task and you'll see them jump up to 2GHz. There's even a neat little applet that you can add to the top panel called "CPU Frequency Scaling Monitor" that will let you watch the processor speed up and down in real time, as well as enable or disable frequency scaling. (Right-click on the top panel bar and select "Add to Panel" to find it; it's under "System and Hardware") --Mike Richards 06:31, 13 September 2007 (UTC)
Wireless card options?
The T61 lists two options for wireless cards the Atheros card and the Intel 4965. Both have their issues right now, has anyone had any success in using a IPW3945 with this laptop? I tried moving the IPW3945 from my T60 to this laptop and it seems to be missing some of the radio connections and did not work. I eventually want to use my IWL4965 card since the drivers are open however the disconnects every 30-60 minutes are getting insane...
Update to this question: My concern with the Atheros card is the signal level reporting issue that some comments on the madwifi dev list indicate have been fixed. Can anyone with an Atheros card verify that they are seeing the correct signal level? Also I shutdown Network Manager and connected to my AP via wpa_supplicant and ifup and the connection has been stable for almost an hour so maybe the problem isn't the driver? --Darrena 01:57, 11 September 2007 (UTC)
My T61 has the built-in Intel 3945 and I'm using the default ipw3945 driver. I've never had any problems with wireless. --Mike Richards 05:02, 12 September 2007 (UTC)
IWL4965 Issues
I think the problem is with Network Manager or the NetworkManager package in Gutsy see my post the NM mailing list regarding this here: http://article.gmane.org/gmane.linux.network.networkmanager.devel/7548
