Re: Debuginfo repositories
Hello, We didn't mean to not include the debuginfo repo in the yum configuration files. I thought they were in there. It wasn't until I was doing more documentation about the changes since SL5 that I noticed they weren't there. We are working on updating sl-release so that the debuginfo repo's are in there. Expect it by the end of the week. As for RedHat yum repositories, you must be thinking about Fedora. I don't have any yum repository configuration files on my RHEL machines. It's all handled through rhn.

If one wants to analyse and tune the performance of the system, the SystemTap is absolutely essential and it needs debuginfo as well.

SL 6.0 on Thinkpad T410s crash on login.
Hi, I tried to install SL 6.0 on my laptop which is Lenovo Thinkpad T410s. During the installation I just chose the 'Desktop' and did not add any more packages. When the installation finished, the system was crashing on the login interface. Here 'crashing' I mean freezing, the time is even stopped. I am wondering is there any suggestion to solve this problem? Thanks a lot. MVH /Sen -- Sen Li Ph.D. student Uppsala University

Anyone have any thoughts on this? I don't think it is related to SL6 itself. Victor Hi Victor, Yes, you are correct - it's not an SL6 issue specifically as the RT2860 drivers aren't included in the SL6 (and RHEL6) kernel. Elrepo.org have previously provided these drivers for SL5 but finding testers for them was notoriously difficult so we simply haven't ported them over to SL6 yet. Now we have a potential tester in you, we (elrepo.org) would be glad to knock up a package for you to test. Would that be OK with you? Regards, Phil Just to tie off this thread, there is now a driver for the RAlink RT2860 Wireless device available for SL6 at elrepo: http://elrepo.org/bugs/view.php?id=120 Many thanks to Victor for helping test the package.
Re: SL 6.0 on Thinkpad T410s crash on login.
Hello Sen, not sure, but I think that the new Lenovo Thinkpad T410s is a laptop with the hybrid graphics (NVIDIA Optimus). It means lots of problems, because Nvidia has no intention to support it in Linux. As far as know, there is no workable solution yet, except disabling of the Nvidia card in BIOS. Good places to start: http://forums.nvidia.com/index.php?showtopic=188184 http://linux-hybrid-graphics.blogspot.com http://forums.gentoo.org/viewtopic-p-6392405.html?sid=3aa6992b33ba45578a93e4d9a2b82087 Good Luck, I have given it up after three days, better to avoid hybrid graphics.

Re: Debuginfo repositories
Hello Troy, thank you for reply. We are working on updating sl-release so that the debuginfo repo's are in there. Expect it by the end of the week. Great news, I have found few bugs, one is nicely reproducible and I would like to report it to RedHat. ABRT + debuginfo will help me a lot. As for RedHat yum repositories, you must be thinking about Fedora. I don't have any yum repository configuration files on my RHEL machines. It's all handled through rhn. Yes, you are right, I am sorry. The last RHEL I used to use was version 4.x. ABRT, SystemTap and all the related infrastructure I really know from Fedora and I naively expected that in RHEL6 it will be used in the same way. Another question: does RHEL6 use Presto plugin and delta rpm? Vaclav M.

Re: SL 6.0 on Thinkpad T410s crash on login.
Take a look here: http://www.thinkwiki.org/wiki/ThinkWiki linux knowledge from around the net about Thinkpads accumulates here, a very nice site. And you can log in and add your own information to be archived for future people in your situation. The T410s has Intel graphics: http://www.thinkwiki.org/wiki/Category:T410s and there's documentation of Fedora and Suse installs, with few graphics problems: http://www.thinkwiki.org/wiki/Installation_instructions_for_the_ThinkPad_T410s My general advice though - usually you're far better off going with a Fedora or Ubuntu style distro on laptops, the enterprise-based distributions update too slowly on the hardware driver front for portable computing needs. An immediate suggestion for your problem - go in in rescue mode, edit /etc/inittab, and change the default run level from 5 to 3. That way you can get in on console and tweak stuff, issuing a startx command to bring up the desktop at will instead of being forced into a buggy state right away. -- Alec Habig, University of Minnesota Duluth Physics Dept. ha...@neutrino.d.umn.edu http://neutrino.d.umn.edu/~habig/

Thanks, Matt Hi Matt, Sorry for not replying. There are two ways of doing this. 1 - simple and easy, no real descriptions, just marking packages as security or fastbugs. That should be easy enough by going through the SL yum repo's. 2 - Having all the detail for each errata. For that you need to have a current RHEL machine and an account on rhn. You download the errata metadata, convert it to whatever you want (if it's your personal spacewalk, I suspect you don't need to convert much) and then push it up onto your spacewalk server.

I've checked the Live CD that I have and it doesn't have /etc/mdadm.conf. The install that I made with the Live CD does have one though, which I find confusing because I thought (incorrectly it seems) that a Live CD install is made from the same image as the Live CD itself. It doesn't have HOMEHOSTsystem but it is set to automount some arrays. In SL6, the LiveCD install first copies the LiveCD image to hard drive. Afterwards anaconda is finishing the install which includes to create /etc/mdadm.conf: # mdadm.conf written out by anaconda This was not the case for SL5 and SL4 LiveCD, where the install was just a copy of the running LiveCD to hard drive.

Thanks for replying! I have switchable graphic card which is intel+nvidia 3100m. I have installed the 5.4 version on this laptop, it worked fine. I will try to disable nvidia in BIOS to see if it works and report back. otherwise, I will stick to 5.4 or 5.5. /Sen On Tue, Mar 15, 2011 at 9:14 PM, Alan Bartlett a...@elrepo.org wrote: On 15 March 2011 20:05, Vaclav Mocek little@email.cz wrote: On 03/15/2011 07:47 PM, Alec T.

Re: SL 6.0 on Thinkpad T410s crash on login.
Have you checked to see if the issue will be resolved by using the ELRepo kmod-nvidia package [1] ? Alan. [1] http://elrepo.org/tiki/kmod-nvidia Yes, I have tried it. Nvidia Optimus is not supported and never will be in Linux - official Nvidia's statement. The similar situation is with ATI's fglrx and their switchable HD5470, which is quite common now. So only opensource drivers with kernel 2.6.35 (SL6 is based on 2.6.32), with vga_switcheroo (http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=6a9ee8af344e3bd7dbd61e67037096cdf7f83289;). As a result you will have poor 3D acceleration, higher power consumption and no OpenCL or CUDA. The best solution is to switch the dedicated graphic card off in BIOS.
