Ubuntu :: Samsung N150 - Screen Half Brightness No Change And Wifi Not Working
Jun 5, 2010
Just installed on my netbook the latest version of ubuntu (10.04). Have seen a few issues with other users however they have seemed to be able to make fixes.My problems are:
- Screen half brightness no change (does anyone have a fix yet?)
- Wifi not working (tried updating kernels, says they're the latest)
- Multi touch not able to be enabled, (again have seen a fix but for some reason won't work)

I'd been trying to get into Linux before I bought it so I figured that I would try to get it onto my new Mac so that I could use it wherever I am. I decided to try Debian Lenny 5.0.3 a whirl after reading about all the different distros available. I've successfully installed it and I can get to it with rEFIt, and I have quite a few things working such as the video drivers and wifi. However, I've had trouble getting it to a level where it'd be usable away from home. Here are the main problems I'm worried about:
1) I installed pommed but I still can't use the brightness keys to change the screen brightness. I'm not sure if there's some other workaround for this?
2) I tried some recommended power management packages (gnome-power-manager) but it doesn't seem to be accessible or functional right now. I don't have any way to control it or get to it that is obvious to me. Is an icon or anything supposed to appear on the task bar when you install or what? Getting some sort of power management on here is important because it gets really lousy battery life otherwise.
3) Being a Macbook, there's no right-click button. Multitouch would be really nice (two-finger scrolling!) but I'd be OK with ANY way to right-click with the touchpad. I have a wireless USB keyboard/mouse combo that works at home at least . . . right out of the box too!
4) I've seen some packages called the Mactel PPA, but they are made for Ubuntu. Since Debian and Ubuntu are so similar, is there any way to make those work on Lenny? I think that if I got those to work, I could fix some of the problems above. Or do I have to install Ubuntu?
5) I just noticed that the sound doesn't seem to work yet either.

I've upgraded to Maverick but now I cannot get my wireless card working. In Lucid it didn't work out of the box, but worked perfectly by wrapping the Windows driver with ndiswrapper.
I noticed when I installed Maverick that wireless is enabled in Network-Manager and it gives me the option to create a wireless network or connect to a hidden network but it's not discovering/showing any of the wireless networks in range! So it seems as though the card is being recognized but the driver isn't working fully...? I tried wrapping the windows drivers, but that didn't change the situation at all.
Details of my system:
Code:
Ubuntu 10.10
2.6.35-22-generic x86_64
Code:
Desktop PC:
Intel Core i5 750

I have just purchased the Samsung N150 net-book. The reason for purchasing was so I could watch movies, listen to music and browse on the go. It came with windows 7 starter and a load of pre installed Samsung crap. I was wondering whether Ubuntu would be a better choice for me since I only really want, Chrome, VLC, Spotify, MSN and Dev++ compiler.
I am very computer literate doing programming at Uni, but have not used Linux before. Also there's loads of Samsung software for extending battery life or something. Will I be able to install that on Ubuntu or not?

I've got UNE 10.10 installed on a Samsung N150 that uses the RTL8192E for wireless. When the wireless works then it generally works okay, but I'm having problems with reboots and long-running connections. This is different to the mass of posts (mainly from 2009) about the card not working at all, so I started a new thread.Basically, 90%+ of cold boots result in a successful wireless connection, with Network Manager remembering my WPA password.
When the wireless is up then it never obviously drops out, but I've got an app with a long-running connection that seems to disconnect itself occasionally. Looking at Wireshark then it appears that there are a number of retransmits, and a big batch just before it disconnects (which implies that the app is dropping its connection because it thinks the other end disappeared). Running the app on another machine with a different card but through the same release of Ubuntu and the app and the same router doesn't result in retries or drop-outs.On the times when a cold boot doesn't successfully reconnect then it asks for the WPA password, then continues trying, then asks for the WPA password again, then continues trying, then asks...and so on until I rmmod and modprobe the driver.
I originally had problems with the machine refusing to restore after a hibernate/suspend, but this was solved by a tip to rmmod the driver on hibernate/suspend and modprobe it on restore.The wireless will now work okay on some restores, but is more likely to repeat the behaviour described above for the failed cold boot.
Code:
$ lspci -nn
...
05:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8192E Wireless LAN Controller [10ec:8192] (rev 01)[code]....
Attached is a file with some snippets from dmesg around the time of the wireless failure, and the log of what it does after a remove and re-add for comparison of the "correct" messages.

I have a Samsung N150 netbook with Atheros AR 9285 WiFi card. I installed Ubuntu 9.10 on it, although this problem happens on other distros too (Network Remix 9.10, OpenSuse 11.2) My wifi card and networks get detected. The problem is when I try to connect to my network, which is protected by WPA key (I don't know if it matters whether it's WPA or not). After I input my network key, the network manager is trying to connect, but obviously cannot, because just prompts me for password again. I can connect without problems to this network from my other computer running WinXP

I'm having trouble locating a way to adjust the screen brightness on fc10... It is only possible to use the monitor's control for now.Yeah my monitor make an annoying whining noise unless you turn it on 100% brightness, but that hurts my eyes.It is so crazy that they didn't put a brightness control in! ( or rather they destroyed working ones of year past, Why? )

I bought a Asus eeepc a few days ago which I really like, with the exception of one thing - windows 7 starter. I like Windows 7, but starter is just bad. I also really like ubuntu, so I've decided to put it on my netbook. I download the netbook edition from the site, put it on a usb drive, and than tested it out - well, my screen is dim, very dim. Changing the brightness setting on the tool bar up top doesn't change anything, and using the function keys does change it, but still keeps it very dim.
I've tried restarting my computer, same thing, I've tried messing around with settings in the battery options, nothing... I really don't want to install it if its going to be this dark, I can see things, but its not very pleasant to use. I'm starting to consider that its the problem with the file I downloaded. Theres nothing wrong with my netbook, everything worked perfectly fine in Windows 7. I use the full version of ubuntu 10.04 on my other laptop which works perfectly fine, I'm not sure why this version is acting so weird on my netbook.

I've an asuspro (more precisely the p2520la version) notebook with the fn+f5, fn+f6 buttons that should change brightness of the screen. But they don't work. For volume it's ok (fn+f11/f12), and if I go in the system settings I c an change manually the brightness (I use kde so there is a bar with which change it). But when I'm outside and the screen brightness is low I found difficult to find the menu settings and the hardware buttons would be better.I've tried adding to the kernel the "acpi_osi=" command but doesn't work.

i had slackware 13.0 on my dell vostro 1320 and it was all good, but since the upgrade to 13.1 i cannot change the screen brightness with ctrl+up and ctrl+down keys..i'm not even sure how to start with this problem. from what i understand these keys 'call' a bios function...? so that would mean that some kernel module is not being loaded?or has the desktop environment lost the key mappings and that is causing my trouble?

I am using Ubuntu linux, and I want fn + up key and fn + down key to change the brightness instead on fn + F4 and fn + F5. I've tried looking for something in the Keyboard Shortcuts menu, but there is no command or key specified to do that. I could make a custom key shortcut, but I can't find the command to change the brightness. Is there a way to make another key do this? My laptop is a Dell Inspiron 1545.

I have faced with some problems:
1- The screen brightness doesn't change. neither the brightness hotkey works nor the brightness applet changes the brightness
2-There is no sound
I had none of these problems with ubuntu lucid.
Here is the output of lspci command:

I installed Ubuntu 10.10 on my laptop and encountered several issues.
1. The Synaptics touchpad is nearly unusable. It is impossible to drag while holding down a button. The cursor will move randomly across the screen instead. It is impossible to right click; a right click is treated like a left click. Double-tapping the dot in the corner does not disable the touchpad.
2. Attempting to change the brightness will kill the screen. The computer is still functioning, and it is possible to perform tasks "blind." Only the screen becomes completely blank.
3. Ubuntu does not always boot up reliably. When it does not, the screen is blank but the computer is otherwise responding.
4. The screen is black after suspend.
5. The computer will sometimes hang when shutting down (showing desktop background). Possibly related messages in dmesg:

I could find on the net to fix the screen brightness keys and get them working so I could increase the screen brightness. Nothing worked.For most or many people, some of the suggestions will work fine. For those of you who can't get them to work and are stuck with Ubuntu 10.04 on the NC20 with a dimmed-out screen, I have a quick workaround:
When you boot and get to the BIOS password prompt, use the function and up-down array keys to control the brightness there. The screen brightness will be carried through to Ubuntu. You might be able to do this at the GRUB prompt. The point is that the BIOS handles the screen brightness before Ubuntu, so it just works.

I'm currently trying to setup a minimal Slackware installation. Everything is well, except for screen brightness/hard disk control via laptop-mode-tools. I was wondering if anyone used it, and if they got it to work on their Slack systems, how they went about doing it.

I tried getting a Belkin USB Wireless adapter:N150 to work in a fresh installation of 10.4 with no success. After reading several forum posts I tried both solutions with ndiswrapper and the XP driver and with the Ralink native driver with no luck.
Code:

I just upgraded from 9.04 to 10.04 and so far I have those problems:
1. Before, everything in my system was in English. Now, half is in English, half in another language (PCManFM, some menus etc). I tried setting up Language Support but it changes nothing.
2. Cursor themes work only when hovering the mouse over "X" buttons in the right top corner of the window. As soon as I move the mouse somewhere else, it goes back to default cursor theme, even though I tried selecting 5 different themes - same result.
4. Hibernation don't work anymore. s2disk saves image to disk and then it resumes it but computer stops on text message along the lines of "Resume completed successfully".
5. Changing volume with keyboard shotcuts no longer works.
6. Smplayer does not display picture anymore when playing movies. The view is just empty. I can only hear the soundtrack. It is using XV filter.
7. PCmanFM that used to worked flawlessly, now after going into 1 or 2 subdirectories stops reacting to clicks on file/folder list. Need to open new instance to be able to do anything and this again would become unusable after visiting 1-2 folders.

I'm clearly missing something small. My Ubuntu machine can see the XP machines in the WORKGROUP, pull files over and even print to the printer attached to one of them. Internet sharing also works. However, the XP machines cannot find the Ubuntu system.

I have a new sony vaio VPCF11NFX/B with a fresh install of Lucid. I am using a VGA-out to a LCD monitor. It shows up and is recognized. I cannot get video to appear on my laptop monitor. Moreover, when I unplug my external monitor, I cannot boot into ubuntu. It brings me to low graphics mode and I can't do anything from there because half of the screen is missing.
