Hey guys, just bought a Y510-KA and found this thread. Great info al around.
I didn't read all the way through yet, so I'm sorry if this info already came up... But here's something new, hopefully...
Regarding brightness:

https://bugzilla.redhat.com/show_bug.cgi?id=470465
Here's a patch (haven't tried yet):
https://bugzilla.redhat.com/attachment.cgi?id=323670
Regarding flipped UVC camera:
1. http://ubuntuforums.org/showthread.php?t=838210 + 4 different patches
2. http://ubuntuforums.org/showthread.php?t=561433&page=2 (someone suggests trying "echo 1 >/sys/class/video4linux/video0/vflip", can'ttry it right now, posting from a different machine)
Hope this helps someone.
Some of you may have a problem with a hot machine that's always ramping up the fan. Here's something I recently came across that will drop the running temp of your machine by possibly 10 degrees Celsius.
You need to add the following modules into /etc/modules. You can do this at the command line or in your favorite text editor, but be sure to do it as root. Add the following to the bottom of the list of modules that are already there (see the proviso at the bottom of the post):batteryThe next time you start your machine, these modules will be loaded at boot, and they go a looooong way to controlling the possible thrashing your machine may undergo.
ac
thermal
processor
acpi-cpufeq
cpufreq-userspace
p4_clockmod
I was consistently at around 61 degrees and the fan was almost always on. I was looking into undervolting the machine, but that never worked. When I added these modules, even with 31 tabs open in Firefox (I'm researching/writing), I'm resting comfortably at around 47 degrees Celsius, and even when it jumps up after some heavy multimedia use, it drops fairly quickly.
For those who want a little more fine-tuned control over their CPU, you can add the CPU Frequency Scaling Monitor and a few other things to help you monitor your specs via applets (little apps that run in a panel).
This installs the necessary applets to start checking things out.Code:sudo apt-get install hddtem lm-sensors sensors-applet computertemp
- Computer Temperature Monitor: Gives you the temp of the CPU and disks
- Sensors Applet: Like the above, but a little more detailed (it gives me my GPU temp on my desktop machine)
- CPU Frequency Scaling Monitor: Allows you to change the frequency of your CPU's. I've added that twice and monitor both cores at once, just for tests.
However, you need to do one more step to enable the CPU Frequency Scaling Monitor's full range power:
This will bring up an ncurses dialog asking if you want to install the frequency monitor with the SUID set. Choose OK, and when it asks "Install cpufreq-selector with SUID root?" choose "Yes." (You'll need logout and log back in to get it running with the options.)Code:sudo dpkg-reconfigure gnome-applets
Now, if you want to change the frequency of the CPU to make it run at a higher or lower frequency (depending on what kind of power you want/need), you can change that through the CPU Frequency Scaling Monitor applet to the panel. You can either choose governors or a set frequency. Ondemand seems like a good choice -- it increases and lowers the frequency as needed. Performance is obvious, Powersave is obvious, and I'm not quite clear on the difference between Ondemand and Conservative; I think Conservative does about the same thing, but slower.
PROVISO
I'm not completely clear on the p4_clockmod module. I searched for quite a while and came up black with good info. Lots of people recommend it, but I don't know if it is necessary or conflicts with anything or even loads if it isn't necessary. It does something other than managing the frequency; as I understand it, it manages the rate that frequency changes, no the frequency itself. If someone else knows, please post.

Hi Wyth,
you're right, brightness has been fixed in 2.6.28+ kernels.
Camera is still flipped, yeah you can flip it back in Cheese, but what about Skype?
Also, does any of you guys got the Infra Red controller to work? If so, which module do I need?
Thanks.
I am using Jaunty Jacalope Alpha version and Yes the brightness issue is fixed.
2.6.28-8

Hi
I have a Linux Gentoo 2.6.27 in a Lenovo Ideapad Y530.
Some issues that i have after reading this topic.
1. ALSA seems resolved for next Kernel. or 2.6.29.
2. Orange keys work and don't work. In Ubuntu 8.10 LiveCD they work without glitches.
Most of the time that keys don't work. Sometimes work after tap them a lot of times. They work 'perfectly' after a few minutes without using laptop (...)
I see sometimes this in dmesg (random appearance) when i try to use them... not always the same output...
This PLAY orange keys produce the same code as the FN+(F9..F12) keys (this works). And they respond when i use the '#showkey' command. But in 'xev' not really or sometimes. Anyway I have them mapped in .Xmodmap and later configured in Xfce4 shortcuts to control 'exaile'. Anyway why they work well in Ubuntu? What kernel config needs?Code:CE: hpet increasing min_delta_ns to 15000 nsec CE: hpet increasing min_delta_ns to 22500 nsec CE: hpet increasing min_delta_ns to 33750 nsec CE: hpet increasing min_delta_ns to 50624 nsec
3. I can not play AUDIO CD. I use dcd for this, and also cdplay. And they don't work in this laptop. I can read/record cdr. I can extract audio CD tracks using cdparanoia. Some one has this problem. It gives a lot IO errors from kernel. It works in *******
lshw:
4. I have problem with brightness. This keys have the same problem as the orange soft keys. But they always work, Fn+up give always second lowest bright and Fn+down gives always the lowest bright. Solution? Kernel 2.6.29-rc5 does not solve the problem.Code:*-cdrom description: DVD-RAM writer product: DVD RW AD-7560S vendor: Optiarc physical id: 1 bus info: scsi@1:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/scd0 logical name: /dev/sr0 version: S801 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc

I also have Y530 and currently don't know hot to makw its mirophones work properly though sound in general works ok... any suggesions?
Thanks.
I usually open alsamixer in a shell. Depends which model you configured anyway.
alsamixer in shell/terminal (in Gnome maybe you also have similar mixer)
Make sure that in playback mode, your mic and front mic are mutted (press M to change state to Mute 'MM').
press tab to go to capture mode. If you want to test your integrated micro:
Change input source to "front mic" (up key)
Capture only from input source (space and raise volume)
If you want raise volume of front mic boost.
Try your favorite recorder.
