Progress on setting up Linux on P750DM-G ... but, backlight/wifi/etc?

On the WiFi, it still detects the networks (using the WiFi Radar app) with the wired connection unplugged, so I know that part of it is working, but I can't actually connect. Maybe I'm entering the key in the wrong place? (It's stuck at "Acquiring IP Address (DHCP)".) Running "dmesg | grep iwl" in console says the Intel AC 7265 is detected, but there's quite a few lines of "L1 Disabled - LTR Disabled". But I now can't remember what console command I used that showed me something is disabled. :/ Also just to see if that would work, I tried USB tethering with my phone's 4G connection (the phone's running Cyanogenmod) and the laptop wouldn't detect it. It did detect the phone's filesystem when I turned tethering off, though.

Hmm... apparently under LMenu -> Preferences -> Network Connections, it only shows Wired connection 1, but has the option to add a WiFi connection. Looks like I gotta manually configure things though, look at the router label, etc ... but that doesn't seem like the way it's supposed to be done (manually configuring IP, DHCP, gateway, SSID, MAC address, etc). Under LMenu -> System Tools -> Network, it isn't finding much of anything there.

OH! Now I click on the icon by the clock (lower right) that says my network is disconnected, it shows the WiFi access points, click that, put in the key ... and it connected. BUT... I'm only getting 1 bar of signal, and I'm like 8 feet from the router with no obstacles in between. Maybe I need to take the laptop apart again and see if I need to hook up an antenna to the wlan module? Or is there something else I can do to change it? My phone (Samsung SGH-T699 running Cyanogenmod) is able to get the signal near the back of the house about 30 feet or so away through about 6 or 7 walls, or about 150-200 feet straight back in the back yard through about 2 walls, although it's spotty there. (Also I'd like to be able to get USB tethering with my phone working, in case I want to use internet where I don't have WiFi but do have cell data service.)

I was talking about the screen backlight, not the keyboard backlight. I can't seem to turn it down, and I'd like to be able to do so to make my battery run longer, and also for situations when a full-brightness screen is undesirable.

For the touchpad, Fn+F1 doesn't do anything. So far the only thing I've been able to do is "synclient MaxTapTime=0" to disable tap to click on touchpad, and "synclient -i 1 -d -K" to make the touchpad not respond for 1 second after pressing a keyboard key, but I have to redo that every time I reboot, and the wait 1 second after keystroke isn't how I want it to behave. :/

Also is there a gui-based utility to modify the CPU and GPU clock speed? I had found something in console (forget what it was now) but would like a graphical utility to do so. I know that with a non-K CPU I can't overclock it, but I want to be able to manually cap it at a lower speed to save battery life when I don't need the extra performance.

Also what's the procedure to enable hibernation / suspend to disk?

Let's block ads! (Why?)
