Catalyst HDMI Black Border
Posted by delightlylinux in linux on December 12, 2012
Catalyst video drivers on Linux have always exhibited second-rate quirks compared to the excellence of nVidia. One such quirk encountered recently is the HDMI black border effect.
As shown in the image, any monitor connected to the HDMI output (direct HDMI to HDMI) will shrink to the center of the screen, and a black border will appear around it.
File Immutable Attribute
Posted by delightlylinux in linux on December 11, 2012
Do you need to set a file so nobody can delete or edit it? Simple! Set the immutable attribute on the file.
Suppose you have an important info.txt file, a frequently asked questions file, a set of instructions, or even installation scripts that exist on a Samba share. Perhaps these files are accessible via SSH or FTP where write permissions are granted. In any case, they must not be deleted or tampered with, even by root.
Acer Aspire S3 Ultrabook and Ubuntu 12.04.1
Posted by delightlylinux in linux on December 7, 2012
“Wow, this is slim!”
“Wow, Ubuntu runs well!”
“Wow, this is lightweight!”
…and a list of other praises come to mind when playing with this ultrabook.
Is there a better netbook or portable computer than the Acer Aspire 722 for running Ubuntu? The Acer Aspire S3 Ultrabook
The S3 is a delight to use, and in my experience, it runs Linux better and faster than the bundled Windows 8 despite a few minor issues.
What follows is my enjoyable experience with Ubuntu 12.04 on what is probably one of the best-looking portable computers encountered: The Aspire S3.
The Seagate Momentus XT Hybrid Drive and the Netbook
Posted by delightlylinux in linux on October 27, 2012
SSDs (Solid State Drives) are fast but expensive and low in capacity while mechanical drives are slower but inexpensive and offer larger capacities. Is there a way to combine the best of both worlds?
The Seagate Momentus XT 750GB hybrid drive attempts to combine SSD speeds with a large 750GB capacity in the space of a laptop hard drive. Does a hybrid drive offer better performance than a regular drive? And, more importantly, how well does it perform in the Acer Aspire One 722 netbook running Ubuntu 10.10 64-bit?
The 128GB Memory Stick PRO Duo Using MicroSD Cards
Posted by delightlylinux in linux on October 17, 2012
“Uh-oh! My memory stick ran out of space. Is 128 gigabytes possible?”
Yes, it is, and it is possible by combining two 64 GB microSDXC cards into a single 128 GB Memory Stick Pro Duo using a dual slot adapter. The result is a single Memory Stick Pro Duo with 128 GB of unformatted capacity.
Acer Aspire One AO756 Netbook Experience
Posted by delightlylinux in linux on October 8, 2012
The Acer Aspire One 722 is an excellent netbook for running Ubuntu, and it even upgrades to 8GB of RAM. Can it get any better?
Since then, Acer has released newer netbooks, such as the Acer Aspire One 756, so, in the never-ending quest to find a better mousetrap, I had to give the 756 a try!
Having acquired a 756 model for myself, it was time to find how it compares to the reliable, time-tested, (mostly) Linux-friendly 722. Have the annoyances been fixed? What is the netbook’s build quality like? Is the 756 faster than the 722? And most importantly, how well does it run Ubuntu 10.10 (my favorite Linux distribution of all time)?
Well, this turned out to be a surprise, leading to several issues I was not expecting. Newer is not always better, and this is a prime example. This review documents my experience and thoughts regarding the Acer Aspire One 756 netbook.
What is the Difference Between RAID01 and RAID10?
Posted by delightlylinux in linux on September 29, 2012
RAID (Redundant Array of Inexpensive Drives) is a hardware technique to improve fault tolerance (the ability to compensate for failures) of data stored on hard drives. There are several variations of RAID, but the common goal is simple: If one hard drive fails, recover data from another.
RAID drives are grouped together into units called arrays. There are two techniques for controlling RAID arrays: Hardware and software. Hardware RAID involves a dedicated hardware RAID controller card, and it is usually faster, more reliable, but more expensive. Software RAID achieves the same result through the operating system and the inexpensive motherboard drive ports, but its performance and reliability are not as good as true hardware RAID.
RAID01 (RAID0+1) and RAID10 (RAID1+0) are two RAID configurations that are easily confused, so here is a brief description to help explain their differences and which is better.
