[Kernel-packages] [Bug 407597] Re: Failed to load x11 FrontEnd module
In Bento Openbox 14.04.3, this bug shows in the $HOME/.xsession-errors. The real issue is that if there is no background on top of the root background, the Openbox menu does not show. The issue is solved by removing the scim packages: scim scim-gtk-immodule scim-im-agent scim-modules-socket Once these packages are removed the Openbox right-click menu shows again, even on a root background (which is sometimes desirable when it's about reducing the load on the system by all means possible on old computers).

Adam, thank you very much for the time you took to solve it and help me with my issue. I confirm this was it.

Hi, I installed the Bento Openbox respin (Ubuntu with Openbox) version 14.04.3 on Asus EEE PC of the same version, 1225b, and seeking for all the best solutions for this little laptop to work correctly, stumbled upon this bug report. Hence I rebooted and removed the external keyboard and mouse I had plugged to work conveniently and met with the same keyboard/touchpad issue as you guys. I applied the solution promoted by enrico on his comment #16, and all seems fine now. I hope it will continue to work right!

[Kernel-packages] [Bug 1246664] Re: "Buffer I/O error on device zram0, logical block 515067"
Hi Damian, According to you output zram does not appear to be loaded, if it was we would see a zram device, ie: /dev/zram0, /dev/zram1 (if your machine has two processors, dual core, core duo, or hyperthreading). You can remove the 3 following files: /var/crash/zram-config.0.crash /var/crash/zram-config.0.upload /var/crash/zram-config.0.uploaded and you can uninstall all the previous kernels and headers which have been installed in your system before the 3.2.0-58. If you fear something works less well, you could keep the two last sets, linux-image and linux-headers, ie 3.2.0-58 and 3.2.0-56. You can use Synaptic to do that (filter with "search > name > linux" then, "search > name > headers", then click on the top of the first row to gather the said names which a related to installed packages). You will gain more or less 120 MB for each old kernel + headers removed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1246664 Title: "Buffer I/O error on device zram0, logical block 515067" Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Precise: Fix Released Status in “linux” source package in Saucy: Fix Released Bug description: SRU Justification: Commit 12a7ad3 "zram: avoid access beyond the zram device" introduced a regression where valid_io_request() checks if request end coincides with disksize (end equals bound).

[Kernel-packages] [Bug 1722536] Re: Displays not properly recognized after upgrading kernel to 4.10.0-37-generic
Hi, I'm not sure it is the same bug, but here is my story: I was running a linux-image 4.10.0-35 in Ubuntu 16.04, with a GPU nvidia 8800 GTS, and using the nvidia 304 driver (nouveau gives poor resolution choice 800x600 or 600x480 as a choice) and the 340 driver gives poor smoothing. Today I ran an update and the linux-image 4.10.0.37 appeared among other packages so I updated, rebooted, then it appeared it would not be able to start the lightdm service! Then I tried startx (I have a config file) but no more success, could not find the screen. So what next, I reinstall the nvidia driver! That's when I saw this message that it COULD NOT FIND the kernel sources! Well here is the thing : no linux-headers no screen! What do I do? I install it of course! 'sudo apt install linux- headers-4.10.0.37' (and the "generic" package as well), then re install the nvidia driver once again, 'sudo start lightdm.service' : problem solved!!!

[Kernel-packages] [Bug 1246664] Re: "Buffer I/O error on device zram0, logical block 515067"
To damian-sawiicki: Do you see a zram-config.conf file under /etc/init ? Another stupid question: did you precisely invoke "dpkg --purge zram- config" ? (When I realized I still had zram-config at work after uninstalling it, I didn't think about "dpkg --purge" and just removed whatever "zram" files I found in the system, especially /dev/zram0 and /dev/zram1 as the machine has two cores, and eventually zram-config.conf if it was still there, but I am not even sure it was still there). To Luis Henriques: I installed the generic i386 kernel and headers in a P4, and it has also been installed to a T60 where it was running with many programs at same time and zram-config installed and at work. All this lasted about 45 minutes and the session didn't fail, although some swapping was occurring. No buffer I/O occurred. Now I am being testing in the P4, zram-config reinstalled, your kernel i386 generic installed, since about 15 minutes.

I will come back later to add information according to the results I will get. Now I will start an additional heavy load by starting Ubuntu Builder and build a custom ISO with your newer kernel and reinstall zram-config to it.

Ok, after more than one hour and a half, with lots of heavy programs started at same time no issue, no freeze on the P4. On the T60 with the 3.2.0-55 generic and zram-config in use the session was exiting really fast and sending the user back to the login screen. With the 3.2.0-56 generic no such issue happened, and no I/O buffer error in either of the two machines. Thanks a lot to the people who fixed it!

Hi, Luis Henriques, I have updated to the new kernel 3.2.0-56 generic from the repositories and the problem is back.

[Kernel-packages] [Bug 1246664] Re: "Buffer I/O error on device zram0, logical block 515067"
Hello, I am preparing the machine for tests as per your pointer to https://wiki.ubuntu.com/Testing/EnableProposed The new kernel 3.2.0-57 generic (and headers) is installed and running in P4 Dell, almost ready to run on another machines, checkbox-gtk installed: the package lacks a dependency to python-dateutil which I had to install additionally as I don't run an Ubuntu Unity version. (This might need a new bug report). I will now start the checkbox-gtk procedure and then start testing how zram-config behaves with the new version kernel. Later I will also try to switch to the 3.2.0-57 pae version and will come back to say how it goes.

[Kernel-packages] [Bug 1246664] Re: "Buffer I/O error on device zram0, logical block 515067"
Hi, I had not found this bug n° #1246664 when seeking for bugs related to zram, and I posted my own, however Oibaf found it and told me: https://bugs.launchpad.net/ubuntu/+source/zram-config/+bug/1247496 linux kernel 3.2.0-55 generic is the one used. I would be very glad to get a 3.2.0-55 generic patched. I would like to know what is the fix that you use? Oibaf also told me "About the "stop" you should open a new bug." : do you confirm the "Stop" line should not be missing in the /etc/init/zram- config.conf file, if so that it is not what triggers problems, and therefore that I should open a new bug for it?

[Kernel-packages] [Bug 1235525] Re: error on sudo parted -l
Hi, I agree with phillw. This message from parted listing option will show in any GNU/Linux distribution, with any kernel when zram is loaded and working, because it's not a logical volume, it is a block device which acts as swap. See the description at the page of the project: http://code.google.com/p/compcache In Archlinux the result is of course the same, you can see here: http://pastebin.fr/29038 This is not a bug.
