Fedora Hardware :: Screen Too Bright (kernel 2.6.32.9-70 Onwards)
Apr 6, 2010
I'm running Fedora 12 x86_64 Gnome and my video card is an ATI Radeon HD 3650. I'm using the open source video driver.After updating the kernel to version 2.6.32.9-70, my LCD display has started being too bright, which makes it barely readable.The problem is still there after upgrading to kernel 2.6.32.10-90. I've even tried to boot a live USB of Fedora 13 Alpha (desktop-x86_64-20100404.17.iso - downloaded from here - which ships with kernel 2.6.33.1-19)

I have a Sony Vaio VGN-FZ340E. I installed Ubuntu about 6 months ago and had a problem-free time with it. I then got busy with other stuff (house work, etc.) and hadn't worked on Ubuntu for about a month. Now I switch on my Vaio with Ubuntu and I find the screen is just too bright.Since 10.04 was just coming up, I thought this would be fixed when I update. I updated, but the screen is still too bright.
I searched the forum for answers and found only some pretty old threads which were about the Fn key combos (which, obviously, doesn't work), spicctrl, etc.So I followed the instructions here. I did just what Step 1: Checking for Module says, but Terminal just doesn't give any output.

I am having problems with my wuxga 1900x1200 laptop display.The machine is a Dell inspiron 8600 with nvidia chipset.I am running driver 175 from the Karmic repo. My problem is when the machine wakes up after a suspend, the display blooms to bright white.The only way I have found to recover is power off the machine. After a bit of research I suspect it may be the refresh rates in xorg.conf, but lowering the values has not changed anything. Here is what I have currently.
Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder75) Wed Jan 27 03:02:48 PST 2010[code]....
orig values were horiz 30-128 and vert 50-90.I'm not sure it's the refresh...

today while using 10.04 Lucid Lynx 64 bit I decided to do something about the low resolution boot screen, I've seen the bugs thread but I thought startup manager would be the way to go Anyway I changed the resolution and the bits to the highest they would go I rebooted and I got the normal coloured boot screen but no logo just text, then I tried disabling text and enabling the boot logo Then I rebooted and the same thing again Then I removed startup manager and the whole boot screen turned bright pink and still had a text logo!

Fedora-13 will not play sound. It's definitely a kernel issue and I am not the only one from what I read elsewhere. Prior to kernel 2.6.28 audio works on this Samsung Q1 Tablet PC. Any kernels from 2.6.28 onwards will not recognize my sound card and therefore won't play sound no matter what. I've proved it running different livecds (Suse, Mandriva, PCLOS, etc.) with kernels 2.6.25, 2.6.27, etc., all with audio. How can I use/import a suitable kernel for Fedora-13 so that it will recognize my sound card (driver snd-hda-intel) on this Q1?

Since the time I upgraded to Ubuntu 10.04, following websites do not load in any browser:
[URL]
These two sites are crucial for me, and I cant boot in back to Vista to just view these two sites.
Is anyone else too facing this issue?
I tested this even on ubuntu 10.10 on a laptop.

I have an ongoing problem in trying to get Audio and video streaming to work with any version of Ubuntu.
Definition of problem: Playing any of the past library of BBC programs either Audio or Video will lock Firefox. Clicking o play a live stream from radio or TV would lock Firefox.
Only resolution was to force quit: Often re-booting Ubuntu would enable the player to work. SOmetimes this needed 4 or 5 re-boots before it would play. Then for no apparent reason it would stop and the cycle would repeat.
I have chased down dozens of threads and tried countless solutuions none of which has worked.
I upgraded to Karmic with similar results. I use the iPlayer a lot, not for downloading just for online streaming and this is causing me untold frustration.
My last upgrade was to Lucid and finally I thought it was cracked as everything seemed to run fine. I run a very trim system with very few installed programs, but within the past few weeks the iPlayer has stopped working pretty much altogether. It will play live stream audio, so fine for listening to the radio as I work, but trying to play any library programs whether audio or video and I'm back to a locked Firefox. I really am at a total loss on where to go with this and I find myself booting more and more into Windows 7 just to be able to function the way I want.
Ubuntu 64 Lucid, AMD Athlon 64 x2 4600+

After I've installed nvidia-vdpau-driver 280.13-1 from debian testing repositories, all the colors on the screen became too bright, except dark colors.
I've tried to change the values from Brightness, Contrast and Gamma, in NVIDIA X Server Settings -> X Server Color Correction, but it doesn't bring everything back to normal.
Either the nvidia driver has problems, or I don't know how to calibrate. But before I installed nvidia-vdpau-driver, I had the nouveau display driver (experimental), and all colors were displayed normally, the same as in Windows 7 and XP.

I install the fc11 from Fedora-11-i386-DVD.iso. The software update has just updated my fc11 kernel from 2.6.29.6-217.2.3.fc11.i686.PAE to 2.6.29.6-217.2.7.fc11.i686.PAE. If I boot using the new kernel, The screen resolution is not correct (everything gets bigger) and the screen goes into blank white screen suddenly after log in.
I have a geforce 8600gt card and installed its driver (for pae kernel) as suggested on this link: [URL]Everything goes well untill I update the kernel.

I just rebooted from an yum update, which updated my kernel 2.6.31-something to kernel 2.6.32-whatever-is-up-to-date-in-testing. My disk layout was LVM2+encrypted root. When I rebooted it prompted me for the encryption password as always. After I entered the correct password the loading screen (progress bar) finishes up as usual. Then, the screen is black.
It just stays in console resolution, but its just black. No typing, no chars, no X-mode, no errors, no VT-switches, nothing... just black. I remember to have started at 2.6.27-something and never had to kernel-update problems, so I dont know why it's annoying me now with todays update. I cant work with the machine any more.

It appears that I have really messed up my machine. I was trying to get matlab working on FC 11 and I ran into libc.so.6 issues, so I put an older file libc.2.3.1.so in /lib/tls/ directory and created a symbolic link libc.so.6 to see if the application would work. Unfortunately at the same time the system did some updates and the system hung, so I ended up rebooting, but now it gets stuck at boot screen (after grub) with a kernel panic - not syncing: attempted to kill init.I just need a way to get to the directror /lib/tls and delete the link and the older .so file I threw in there. How do I get this accomplished. I cannot get even to a shell from the boot screen.

I have Fed 12, running on kernel 2.6.31.5-127.fc12.i686 I have newer kernels installed, but they will not boot into X.
The updater installed the kernel 2.6.32.21-166.fc12.i686. I can boot into runlevel 3. But if I then give the command startx, I almost get an x-window, I can see the top and bottom, ermm, wadjecallems, beams, but the screen is blank, and then the machine freezes. I can only switch off.

Well, to start off my graphics card didn't work but I got that fixed.
When I start up and the login screen appears it no longer says my username and Other.. under it. It only displays Other.. I have to click that type in my username and then my password. When I log on the Auto Bug Reporting tool pops up and says 3 things crashed
I can't change my system time, shutdown or reboot under system or my username in the top right hand corner. I have to su and manually type reboot or shutdown to shutdown. It is like the computer is completely restricting me from using it.
When I try to get into my firewall an error comes up
I cannot mount anything:

my problem is on installing nvidia driver on fc12 32bit but, first of all, as i understood the pae kernel requires more than 4gb of ram,i have a 2.2 ghz cpu with 2 gb ram,but when i run command:uname -r it answers: 2.6.31.5-127.PAE [i have fc12 32 bit] when we try to download linux we have a 32bit edition or 64bit edition,do we have an edition which is only for pae? or when we install for example the 32bit edition on a computer with more than 4gb of ram then the kernel automatically will change to be a pae kernel??

there is an issue with the way the Linux Kernel addresses memory by default and the graphic drivers for my Asus G1Sn. I have a patch that I had compiled against a custom kernel for 2.6.27.xx how ever it does not work with the latest kernel in Fedora 11. It is beyond me to rewrite the patch to work with a different kernel.

I use a pretty fresh installed RHEL 5.4, which should be very similar to Fedora. After the basic installation I installed xen and xen-kernel via yum with no errors. I can select the xen-kernel at boot time. But after booting the normal kernel shows up.
[root@noname boot]# uname -r
2.6.18-164.11.1.el5
My /boot/grub/menu.lst looks like:
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
[code]....
I can't see anything wrong and I did not change/try anything.

I've been using Fedora 12 for about a month, and i'm very happy with it. Even tough, there's only one thing that worries me, and is giving me problems at the same time. I'm getting an error from: syslog@localhost that says: kernel:Uhhuh. NMI received for unknown reason b1 on CPU 0 kernel: Dazed and confused, but trying to continue. Kernel: seems to be a problem, likely on the PCI Bus
I'm not able to reproduce the problem every time i want, but, sometimes happens when i activate the snow effect combined with the cube effect, using kwin. My computer and OS specifications are: Pentium IV HT(disabled) Nvidia Geforce 8400gs 2 Gb Ram DDR2 (1xGB, 2x512) Hard Drives: 2x80GB Using Fedora 12, KDE 4.4.1, with Nvidia privative drivers, nouveau disabled

My laptop has only 2GB of RAM so I don't think I need the PAE kernel, also there are some drivers that I want to install, they were built for non-PAE kernel.
So far I read that I have to change the :
/etc/sysconfig/kernel
---------
# UPDATEDEFAULT specifies if new-kernel-pkg should make
# new kernels the default
UPDATEDEFAULT=yes
[Code]....

From F12 to F13. Is there anything I should remove before updating? I have few programs isntalled from source/binary installers in /usr for example. Would it cause problems?
And is there any chance to be able to switch from a 32 bit kernel to 64 bit kernel during the update? The hardware is capable of this.

I used Backtrack 5 and Fedora, basically I'm trying to install my wireless card but I don't have these installed to make && sudo. I burned the iso images for backtrack and fedora and booted my computer from them but can't figure out how to install kernel-devel on backtrack for example. I dled yum onto my flash drive but can't figure out how to install it.
