Unable to start xorg after latest nvidia update

Hi,
I have NVIDIA GeForce GTX 750 card. I did update to version 346.47 of nvidia driver and figured out that after reboot SDDM dont start. I disabled login manager and tried to start xorg server manually but without success. I see that there is segmentation fault in log but don't understand where it comes from exectly.
Output of /var/log/Xorg.0.log:

In addition, in order to disable sddm I downloaded latest Arch linux installation CD (2015.02.01) but I was unable to start PC with this version. Loading stuck after first 3 lines, after "triggering udevevents".
I had old version 2014.08 and it worked ok.
Thanks,
Alexey

I just wanted to echo eugeneyche's comment. I ran the same steps mentioned by ElectricPrism but that didn't really fix them. I had to add nomodeset to my kernel parameters. I now want to know what's really going on. For the record, this was my backtrace:

Error after latest nvidia update...missing libpangox?

Latest nvidia update (304.60-1):
$ nvidia-settings
"nvidia-settings: error while loading shared libraries: libpangox-1.0.so.0: cannot open shared object file: No such file or directory"
Closest thing is libpango, libpangoxft....

Or recompile nvidia-settings. Here's a snippet of how I do it (in a totally different distro), from nvidia's nvidia-settings sourcecode:
if module_installed "gtk+-2" ; then
# Build nvidia-settings from source
cd nvidia-settings-$VERSION &&
# xf86vmode.h has been removed in xf86vidmodeproto 2.3
if [[ ! -e /usr/include/X11/extensions/xf86vmode.h ]] ; then
sed -i -e "s:#include <X11/extensions/xf86vmode.h>:#include <X11/extensions/xf86vmproto.h>:" src/libXNVCtrlAttributes/NvCtrlAttributes{,VidMode,Glx}.c
fi &&
make clean &&
make -C src/libXNVCtrl &&
make || exit 1
module_installed is distro-specific - of course, it's checking whether gtk+-2 is available, FYI.
Edit: Corrected sourcecode file

Leopard slow starting up after latest update

My MAC Pro is very slow starting up after latest update. Before it took 15 seconds and now takes approximately 8 or 9 minutes. There is a blank blue screen for the entire time, i have repaired disk permissions but this has not helped either. Can any one suggest anything else.

Download an appropiate utility such as Onyx, etc., and purge all caches, user and system. Also do an [SMC reset|http://support.apple.com/kb/HT1411] and a [NVRAM reset|http://support.apple.com/kb/HT1379]. When you repaired permissions, you also repared the disk itself, right?

VMware wont start after latest kernel update!

Okay when i went to reboot it went to boot into arch but wile it was loading the vmware modules it would stay stuck at loading vm communication interface socket family and would just stay there the only way i could even boot into arch was to edit my grub so i could login and at least comment out vmware i tried to reapply the vmware patch fix that was on the wiki and had no luck also tried reinstalling + reapplying patch after words and still no luck I'm hoping this is happening to someone else as well and not just me (mean i know lol) I also tried virtualbox but seems it has it's own mess of problems as well after latest kernel update.

I have tried rebuilding the the kernel image and even tried reinstalling grub with no luck. After not having a usable system for several days I ended up just having to reinstall and maybe found out more about the problem. Using the net install image and a 64 bit install this time making a EXT2 boot and a root partition of JFS right after install I get a panic during boot about how the system can't find a valid filesystem on what would be root partition. Even when passing the "rootfstype=jfs" to the kernel line in grub it still errors out telling me that it is "Bailing out, your on your own. Good luck!" (pretty funny error messages if you are not ripping your hair out). After that I redid the install this time making a EXT4 root partition and everything is working.
It seems to me that this all points to a problem with JFS on 64 bit systems, my other systems are all 32 bit and usign JFS root just fine... can anyone else confirm this?

Applications crashing after latest security update??

So i was prompted to download the new security update and the newest version of iTunes today. i do so, and upon start-up, i open adium and try to chat with a friend. before it could even open the IM window, adium chrashes. I updated adium and it still does the same. I then attempted to see if there were additional updates and the Software Updater also crashes instantly. i havent noticed any problems with other programs yet, but can anyone help me out on this one?
and the problems didn't start until AFTER the security update was installed

Some general advice on updating:
It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
So before you do anything else:
If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
Turn off sleep mode for both screen and hard disk.
Disconnect all peripherals except your keyboard and mouse.
1. Repair Permissions (in Disk Utility)
2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
3. Download the correct version of the COMBO update from the Apple download site.
The Combo updater of Leopard 10.5.8 can be found here:
http://support.apple.com/downloads/MacOS_X_10_5_8_ComboUpdate
If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
Full details about the 10.5.8 update here: http://support.apple.com/kb/HT3606
More information on using Software Updater here:
http://support.apple.com/kb/TA24901?viewlocale=en_US
Using the Combo updater ensures that all system files changed since the original 10.5.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.5.7 to 10.5.8. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
Now proceed as follows:
4. Close all applications and turn off energy saving and screensaver.
5. Unplug all peripherals except your keyboard and mouse.
6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
8. Once your Mac is awake, repair permissions again, and you should be good to go!
If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious!
9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a weeks or two while you regularly check their websites for updates. This applies particularly to plug-ins for Safari 4.
N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
Lastly, Apple's own article on the subject of Software Update may also be useful reading:
http://docs.info.apple.com/article.html?artnum=106695
If you are updating Safari (or just have):
Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If you have installed an OS update and Safari is crashing, the very first thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari.
Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party add-on.
Additional tips on software installation here:
http://docs.info.apple.com/article.html?artnum=106692
To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
Again, the advice is to remove all Input Managers from the following directories:
• /Library/InputManagers
• ~/Library/InputManagers
especially prior to system updates (they can always be added back one-by-one later).

I Have the same issue on a brand new iPad mini 2. My battery is only lasting up to 5 hours. I went on chat with Apple last night and they said my battery is fine and its a Safari issue. I'm literally losing 1% every 3-4 minutes. I tried recalibrating my battery, signing out of iCloud, shutting off all locations, turning off background app refresh, restoring network settings, restoring all, and finally restoring from iTunes with no luck. This is just awful. I got this iPad so I could use it on my long flight for a trip I have coming up, and unfortunately, it's not going to last that long, plus I'm concerned about how many times i will be recharging my battery because of this since battery's do have a life cycle dependent on the number of charges. This is frustrating and needs to be fixed ASAP and addressed by Apple.
By the way, Apple told me to bring my device to the Apple Store because it's still under warranty. That's great and all, but I'm going to waste my time if there is no fix for this issue.
Ok so you want Apple to address the problem, but yet you don't want to take it to them just in case they can't fix it? What if they can fix it? Complaining here certainly won't fix it.

Same thing happens when i click restart.
No difference when i run it in Safe mode. And it won't let me create a new profile either. Is there anyway else i can extract my bookmarks? This is driving me crazy!

Did the crash reporter send any crash reports? 
You can see the crash reports in this folder:
"C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Crash Reports"
See: http://kb.mozillazine.org/Breakpad
See also [[Firefox crashes when you open it]]
Create a new profile as a test to check if your current profile is causing the problems. 
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]] 
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" 
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files) 
See http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox 
If that still causes the same problem then do a clean reinstall and remove the Firefox program folder.
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data when uninstalling.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

ITunes won't open after latest OSX update

AFter latest OSX update iTunes won't open. Reinstalled iTunes. Reinstalled OSX update. When I click on icon in applications or in finder nothing happens.

This is what worked for me and others--original post found on this thread: Yosemite slow opening and cannot open itunes
This solved my question by Linc Davis.......
According to multiple reports on this site, Apple Support has given the following instructions to others who had a similar problem. I can't confirm that this procedure works or that it's necessary, but it won't leave you any worse off than you are now.
First, back up all data.
Select the iTunes icon in the Applications folder and open the Info window. Click the padlock icon in the lower right corner to unlock the settings.
In the Sharing & Permissions section, change the Privilege setting for each Name in the list to Read & Write. Close the window. If the settings aren't visible, click the disclosure triangle on the left so that it points down.
You should now be able to drag the iTunes application to the Trash and empty. Your iTunes data won't be affected.
Click the iTunes link at the top of this page, download the installer package and run it.
If iTunes still doesn't launch, or if you can't complete the procedure, reinstall the OS.

'The installer has insufficient privileges to modify this file C:\Program Files (x86)\Common Files\Apple\Apple Application Support\Web kit.resources\inspector\Images\Spinner Inactive Selected.gif.'
That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
XP instructions in the following document: How to perform disk error checking in Windows XP
Vista instructions in the following document: Check your hard disk for errors
Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards?

After latest security update my MacBook is not finding any network and I think is not really turning wifi on. Has anyone encountered similar problem?

Checked the older discussion of the same type and found solution, well kind of... Thanks to other people who tried it, I just cannot remember their names at the moment. So, the solution for me was to turn off the firewall in the system preferences and suddenly lo and behold there was my network.

In over three years, I have yet to have a problem or meet someone who has.
Most never have an issue.
As this is a support forum, designed for those with issues, of course you will see problems here ( many self inflicted). If you visit a hospital, you are likely to see many sick people, even though most are not sick.
It is really up to you, but most users never have an issue.
