• LSI MegaRAID in Linux Ubuntu / Centos Tutorial Setup Guide megacli


    Usually when I come across a system like this, Ijust flash the firmware to an IT mode so we get just an AHCI system with JBOD, but sometimes it is not practical for remote systems or if we fear that flashing is too risky if something goes wrong. In this case, we unfortunately have to use LSI/Broadcom proprietary CLI tools (megacli) to even make the drives visible. Step 1 - Download MegaCLI The official broadcom packages lack .deb packages and only have .rpm for........
  • i915 nouveau Nvidia GPU not starting lightdm Xorg failing solution for Could not determine valid watermarks for inherited state


    It may appear to be an Xorg or lightdm/gdm/mdm error but in reality for many users with this issue, it's a driver conflict and issue. I had a system that had two GPUs, an Intel and Nvidia GPU. The only thing that got it working was to remove the nouveau driver and blacklist it so it never came back, then the Intel GPU works fine without these issues. Solution sudo rmmod nouveau add nouveau/other driver to blacklist edit th........

  • Linux how to compile binary with static sharedobjects embedded instead of dynamic to use on multi-distributions and avoid glibc compatiblity issues


    One simple flag to configure will create a makefile that statically links all the shared objects and embeds them instead the binary execute. This means as long as you have the same architecture that things should run. Eg. if you have an old version of Debian with a different version of glibc, then this will solve that problem. ./configure LDFLAGS="-static" To test that it is really statically linked run ldd: ldd src/wget........

  • Realtek r8169 1gbit/1000mbit NIC/Ethernet Goes Down/Halts on Large File Transfer/Heavy Network Usage


    This is obviously a bug in the r8169 kernel module and it seems to affect a lot of people. I upgraded to the latest kernel and hope this won't happen anymore, as it is a very serious error. This is especially serious for those who are running servers with this chipset, who can afford for the NIC to randomly go off-line for no apparent reason?
