[Bug 1365844] Re: 0bda:8178 buggy driver rtl8192cu
Hello Chris, I'm sorry that it has taken me so long to respond. The truth is that none of the hoped-for fixes in the upstream kernels worked. I waited awhile to see if things would get better, but they have not. Here are my latest experiments, and the results... I downloaded and installed Ubuntu 14.10-beta2 today, and after updating it, the kernel (as identified by the output of uname -r) was 3.16.0-20-generic. That had the same bug, so no joy there. I then went and downloaded the latest package for the latest upstream kernel: linux- headers-3.17.0-031700rc7-generic_3.17.0-031700rc7.201409281835_amd64.deb Installed this, rebooted, and confirmed that I was now running kernel 3.17.0-031700rc7-generic. But wireless was broken as before. Removed the upstream kernel, ran update-grub just to be sure the system would be bootable, and rebooted. Back in kernel 3.16.0-20-generic and applied my workaround. A reboot later and I was OK, wireless fixed, but not in a nice way. I decided to give another distro a try, in particular, Linux Mint Debian, which is based on Debian Testing. Same bug exists there, and same workaround solves it. This is running kernel 3.11-2-amd64. Well, at least it's not just a Ubuntu thing. Let me know if you have any other experiments that you would like me to try. best regards, Paraquat -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1365844 Title: 0bda:8178 buggy driver rtl8192cu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1365844/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1365844] [NEW] buggy driver rtl8192c
Public bug reported: Driver rtl8192c for a Realtek USB wireless card is buggy. I can connect to wifi, but soon the connection is dropped. This particular bug has probably been around awhile. Others have reported it, though I cannot find such reports here in Launchpad even with a search. A solution for this bug has already been found and published by programmers. I used this solution - it works. I will post it below in its entirety. I am running Ubuntu 14.04. When I discovered this problem, I downloaded and tried Ubuntu 14.10-beta_1 and was surprised to see that it still has this bug. So I am reporting it now in the hopes that it will be fixed before the final 14.10 release. OK, no more talk from me. Below is the info I found online, raw and uncut... = Wireless Realtek chipsets that are running on the default rtl8192cu driver, often loses connection and run below their proper speed. That's because of a bug in the rtl8192cu driver. For instance, this Realtek chipset is present in the Medion MD 86498 USB wireless dongle. The chipsets involved, are the RTL8192CU and the RTL8188CU. Luckily there's a solution that'll make such a chipset run stable and fast, namely replacing the defective driver by a better one. This solution is necessary for the following operating systems: - Ubuntu 12.04 - Linux Mint 13 - Ubuntu 14.04 - Linux Mint 17 This is how to do it: 1. First check whether the buggy driver rtl8192cu is active in your operating system. Open a terminal window: Click on the grey Ubuntu logo (Dash home). Query: terminal. Click on Terminal. Use copy/paste to transfer the following line into the terminal: lsmod | grep rtl Press Enter. When you see one or more times rtl8192cu in the terminal output, then it's active. In that case proceed with step 2. 2. Disconnect your wireless connection (unplug the USB adapter that contains the Realtek chipset), and temporarily connect to the internet by means of an ethernet cable (or by means of another wireless chipset that does function well). 3. Now install some applications for building the right driver. Open a terminal window: Click on the grey Ubuntu logo (Dash home). Query: terminal. Click on Terminal. Type (use copy/paste): sudo apt-get install linux-headers-generic build-essential dkms git Press Enter and submit your password. Please note that the password will remain invisible, not even asterisks will show, which is normal. Wait until the installation has completed. 4. Now download the source code of the right driver as follows. Copy and paste the following command line into the terminal: git clone https://github.com/pvaret/rtl8192cu-fixes.git Press Enter. 5. Set it up as a DKMS module: Copy and paste into the terminal: sudo dkms add ./rtl8192cu-fixes Press Enter and if prompted, submit your password. Please note that the password will remain invisible, not even asterisks will show, which is normal. 6. Build and install the new driver: Copy and paste into the terminal: sudo dkms install 8192cu/1.9 Press Enter. 7. Refresh the module list: Copy and paste into the terminal: sudo depmod -a Press Enter. 8. Blacklist the faulty driver: Copy and paste into the terminal: sudo cp ./rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d/ Press Enter. 9. Reboot your computer. 10. The problem should now be solved: disconnect the temporary ethernet cable and insert the Realtek device again. With the following terminal command you can check whether the right driver is active now (copy and paste it into the terminal): lsmod | grep 8192 Press Enter. In the terminal output you should see that the new driver 8192cu is active. You should see no mention anymore of the old driver rtl8192cu. Note: a possibly surprising side effect might be, that the light on your wireless card is blinking constantly now. That's normal: the light is blinking whenever data are being sent or received.

[Bug 819661] [NEW] Xubuntu 11.04 windows misconfigure
Public bug reported: I installed Xubuntu 11.04. Runs fine for a few days. Then one day boot it up and windows are seriously misconfigured. By misconfigure, I mean the border around the windows disappears. Some windows (like Firefox) peg themselves to the upper left corner. Trying to open the drop-down menus in the windows with a mouse click fails - then menus open and immediately close, making it impossible to select anything. Basically, the entire desktop becomes unusable - almost no applications work as expected. I've seen this on two separate computers now, both with Xubuntu 11.04. I found that switching to the plain XFCE4 desktop finds the same bad behavior as Xubuntu desktop. The problem occurs randomly, immediately upon user log-in. I found a way to fix it, but the fix is only good for maybe a few days and then it recurs. No pattern - it happens whenever it happens., and then won't go away until I apply my fix. So I installed Lubuntu desktop and am using that for now. The problem doesn't recur if I stick with Xubuntu, but if one day I switch back to Xubuntu, then it will happen again eventually. My fix is a lousy one. I've got to log in as another user, open a terminal, su to root. Then cd to my home directory and delete all hidden files and directories. For example, if you are user john then log in as somebody else, open an xterm and do this: su cd /home/john rm -fr .[a-zA-Z0-9]* I can then log out, log back in as user john. Now my desktop works fine. Of course, I've blown away all my configuration files (Firefox bookmarks and extensions, for example). So I've gotten in the habit of saving my bookmarks file. I haven't been able yet to narrow the problem down to a specific configuration file. I tried just deleting ~.config but that didn't solve the problem. It's probably just one broken file, but I don't know which one. This launchpad bug reporting software only allows me to add one file attachment, but I wanted to send you three. So I uploaded the three screenshots to my own web site and have included the links below. Please view these. An explanation for each one: Firefox pegged to upper left corner, no window borders http://www.itmighthavebeen.com/graphics/bugs/pegged.png Firefox and Xterm windows, no borders http://www.itmighthavebeen.com/graphics/bugs/firefox-and-xterm.png Normal view - what it looks like before the borders disappear http://www.itmighthavebeen.com/graphics/bugs/normal.png ** Affects: xubuntu-meta (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/819661 Title: Xubuntu 11.04 windows misconfigure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xubuntu-meta/+bug/819661/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 559785] [NEW] desktops added to panel cannot be saved
Public bug reported: Lubuntu Lucid now has the ability to add additional desktops (rather than the default of just 2). Great news, I love having at least 4 desktops (to avoid window clutter). Unfortunately, I must recreate them anew every time I reboot - the system always reverts to the default of 2 desktops. Seems to me that it should work like Gnome, where my preferred setting of 4 desktops would be saved from one session to the next. Other than this, Lubuntu is functioning flawlessly for me. Thank you for your attention, and best regards. ** Affects: lubuntu-meta (Ubuntu) Importance: Undecided Status: New -- desktops added to panel cannot be saved https://bugs.launchpad.net/bugs/559785 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
