OpenSUSE :: 64-Bit Desktop Kernel Does Not Use NX CPU Flag
Dec 1, 2010
I recently install 64-bit OpenSuse 11.3, the first time I'd used Suse 64-bit - I have to say it has been all good so far, which is great. However, today I was experimenting with a tool that tests vulnerabilities which should be remedied if using an NX capable processor. I am running 2.6.34.7-0.5-desktop on an Intel Core i7. I downloaded a 64-bit compatible version of paxtest from :

Running it I was surprised to see that the NX capabilities of the CPU do not appear to be honored. Here are my results:

From my understanding, NX was one of the big deals a few years back and was a main feature provided by the PAE kernel. I would have thought the default 64-bit kernel would have included NX support. I also thought per NX bit - Wikipedia, the free encyclopedia that NX support has been in the kernel since 2.6.8 I looked in config-2.6.34.7-0.5-desktop but did not see anything related to NX/XD config wise, other than DEBUG_NX_TEST What am I missing here? Shouln't this test fail in the Executable [bss, stack, etc.] tests on 64-bit with a NX capable processor?
I'm just installed OpenSuse 11.3 (64) on a 30gb SSD, hoping to get virtualbox 4.0 running to virtualize an instance of Windows 7.I went through some pain with my Nvidia video card and actually getting vb to install, but through lots of searching and tinkering got here.I created a vm in the vb control panel, but when I go to start it I get:
Code: Failed to open a session for the virtual machine Win7Main. The virtual machine 'Win7Main' has terminated unexpectedly during startup with exit code 1.
I have a system running openSUSE 11.2 with Desktop and XEN kernel, as well as Windows 7 (not by choice though...). I have noticed a strange time issue, with Windows 7 and the desktop kernel the time is correct (like for example now: 1:32 PM) but in the XEN kernel it is ahead several hours (6:32 PM). If it was an issue between openSUSE and windows then I would think that it is a problem with the system clock but I don't know what would cause a time issue between kernels like that.
differences between Kernel Default and Kernel Desktop? I've found some past threads like this link and this other link, and some other google info, which suggest the only difference would be the io scheduler. Also, I see the default grub choice is "Desktop" and not "Default", so I take this as a suggestion to prefer one over the other.
However, my broadcom 4312 wireless only works on the "default" and not on the "desktop" kernel, so I guess there must be other differences. I just want to evaluate which one is the less long-term risk option to go.
I'm having trouble getting PPTP to work on my Gentoo system. Kernel options relating to PPTP:
Code: CONFIG_PPP=y # CONFIG_PPP_MULTILINK is not set # CONFIG_PPP_FILTER is not set CONFIG_PPP_ASYNC=y CONFIG_PPP_SYNC_TTY=y CONFIG_PPP_DEFLATE=y CONFIG_PPP_BSDCOMP=y code....
I've tried emerging with and without the mppe-mppc flag on ppp, as well as putting the PPP options from the kernel to modules. No luck.
Is there a way to boot any current kernel without the nolapic flag on ICH8-based intel T7300 systems? This system works fine with the last 2.26 kernel from FC8, but due to EOL of the security updates I tried to install FC11 and FC10. The first sign of trouble is that their installation only works with acpi=off or nolapic options. As those options disable either fan-control or the second cpu-core I consider them undesirable. Is there a recent correctly working kernel available? Or do I have to downgrade to a distribution that uses a 2.26 kernel?
I understand that the new 11.2 version has a new kernel optimized for desktop use. Can someone tell me or show me where I can find the new kernel configuration options? I would like to see what options they choose to change.
When I installed the suse11.3, I running the "uname -r",the system shows "2.6.34-12-desktop",for some reasons,i need the kernel header for "2.6.34-12-desktop". I down the "kernel-source", "kernel-default" and "kernel-desktop" and I check the "/usr/src/" path, but only have these stuff "linux-2.6.34.7-0.7 linux-2.6.34.7-0.7-obj linux-obj", where can I get the kernel -header for "2.6.34-12-desktop".
Never thought much about it until now a but is it possible to get the desktop kernel at install with 11.3 DVD ? I always get default-kernel and have to do the kernel dance to get the desktop-kernel I prefer. I'm familiar with the multiversion = kernel-desktop and methods to retain different versions. Just wondering.
After migrating from openSUSE-11.1 to openSUSE-11.2 together with a few further online updates including a kernel upgrade to 2.6.31.8-0.1-desktop, my system started freezing a couple of times for two days.
I made up my mind googling for "linux freeze", found a hint saying, that 2.6.31.8 causes trouble, fell back to 2.6.31.5-0.1-desktop, and voila: the problem is gone. What a relief!
Finally got around to updating from 2.6.31.8 and was surprised at the slew of warnings issued during the install. Rather than post them here, see: pastebin - Someone - post number 1792805 I would have bet money that the machine wouldn't boot after this, but it in fact did (whew). Since the kmp modules were not updated with this new kernel, I have merely suspicions....any one have the real reason for these warnings? Same type of warnings occured (thou I didn't copy the output) when I installed the ATI prop driver rpm. everything seems to work as normal so far, but it was so very different than many previous updates that I'm a bit leery.
my friend updated kernel today and it "stopped working" and I was asked to fix it he is new to linux, and I don't have physical access to that notebook from what I know main problems are:
1. no network devices exist (except for loopback) 2. sound card driver is missing (nVidia MCP79) 3. in grub menu after choosing new kernel uname -r sais the old one's version
wifi card is atheros, but I don't know specific model.
A few upgrades ago, I had also a desktop-kernel installed. I tried starting with the standard and the desktop kernel, but could not see a difference. Why this desktop-kernel and what's the difference with the standard kernel? HP laptop with Intel(R) Core(TM)2 CPU T5600 - OpenSUSE 11.3 -KDE4.4.4
On a fresh install 11.3 gnome I am getting an update freeze on the kernel-desktop-2.6.34.7-0.5.1. This is on the initial software update after first log in on fresh system. It downloads the package and freezes during the update and causes all my other updates to reload. I went to init 3 and ran zypper update and saw that it made it to 91% and then stopped. After that I usually get a corrupted install.
I just updated to new 2.6.38-18 kernel and headers. Now the latest Ati 11.2 driver wont install completely and I cannot get any X. So I removed the ati drivers to use the opensuse drivers but kde wont start now (dont know what the issue is.. maybe someone can poitn me out the the correct log file to look for errors).. I am using gnome now. Anyone knows how to get ground this and install ati drivers.
I have an nVidia radeon x1300 series running on my suse 64 bit system. The problem is when I try to enable dual head it tells me that I dont have enough virtual memory so when I add the: Virtual 3840 1200 under the screen section it works for a couple of minutes and then bom! it freezes up no mouse no keyboard response and the screen gets all distorted. whats odd is that I can still ssh to the system. The following is my current xorg.conf without the Virtual flag.

# /.../ # SaX generated X11 config file # Created on: 2010-12-19T10:38:36-0500.
opensuses GRUB is primary and Kubuntus is chainloaded.
The problem occurred after I tried to boot kubuntu for the first time since I installed opensuse. Kubuntu didn't boot. so I probably set up chainloading wrong. No big deal, this I can fix.
The big problem was that after trying to boot Kubuntu no OS was marked as "Boot" in MBR. This is VERY strange. somehow the boot-flag is removed!
After setting the boot-flag (with a live-CD) everything works again. I can reproduce this.
I've tried to find answers but could'nt find any.
Is GRUB supposed to remove the boot-flag when chainloading? have I found a bug?
I have been using Opensuse 11.4 for the past 3 months and for the past 2 weeks the system freezes regularly due to multiple errors.Iam using Kernel 2.6.27.6-0.7-desktop under KDE4 with regular updates

I recently installed 11.3 from DVD Am using Ubuntu Lucid Grub2 bootloader as I have several OS's Updated Grub so that the new kernel version 4 would boot but it boots to a command line... What has happened to my desktop?
I have installed OpenSUSE 11.3 64 bit and want to install VMWare workstation 7.1. I have run the install script for VMWare without any issues. When I start the VMWare Workstation I get a window saying this: Before you can run VMWare, several modules must be compiled and loaded into the running kernel. Kernel Headers 2.6.34-12-desktop Kernel headers for version 2.6.34-12-desktop were not found.
Now I've got debug, default, desktop, ec2, trace, vanilla, xen installed im my system. I usually only boot with desktop, and I was wondering if it is OK to remove other stuff except debug, default, and desktop.
The computer and system in question is the laptop from my description and openSUSE 11.3 with a different kernel from this repository :[URL]..free to move this thread if it should reside in the beta/prerelease forums section. The IMHO relevant information about my hardware and system is shown below.
The kernel I'm using :

I used to sync my local directories via smb4k plus synkron to the server. It works like a charm including kernel 2.6.38.BUT with 2.6.39 it doesn't. /var/log/messages says:
Code: May 25 18:37:01 linux-yg22 sudo: AW : TTY=unknown ; PWD=/etc/samba ; USER=root ; COMMAND=/usr/bin/smb4k_mount -s -t cifs -o
I'm having an issue when I'm trying to install SuSE linux onto my desktop.I go through all the steps and everything looks okay, but when it starts to install the packages, I get an error message that basically says:kernel.desktop - unable to install, exit status 127.I have a ATI X1950 video card in the computer, as well as a AMD 64 FX CPU in the system.
