The latest versions of the distribution of Canonical have brought many new features and improvements but have not been spared to include some problems. The most serious of all, by far is affecting the battery life on laptops , and that makes Ubuntu Ubuntu 10.10 and 11.04 whole lose many on these computers.
Metalbyte remarked on month and a half ago to discuss the Linux kernel 2.6.1938, which is responsible for a situation which for now remains unsolved: the Linux kernel has gained ground in many sections, but since then
there is a big problem with power management .
Phoronix had already warned of this issue, which has also been addressed in UbuntuForums, Fedora Forum in the Ubuntu bug tool and certainly in many other places, and the issue has again be revealed by analysis 11.04 Ubuntu has appeared in Tom’s Hardware and emphasizes precisely the issue:
“In regard to performance, there are good reasons for certain users upgrade [Ubuntu 4.11]. There are also reasons for some users to avoid this distribution by any means. Linux gamers can enjoy substantial improvements, while mobile users will suffer a loss of battery life dramatically. “
arguments are not lightly thrown: the tests conducted by Tom’s Hardware again to reinforce what had been discovered in the past , and the worst is that the solution has not yet been produced.
Thus, the kernel thing 02/06/1939 improving slightly, and it seems to have evolved a bit in the recently announced 3.0 kernels, but in reality the problem persists and is still very serious for laptop users, you’d better use distributions that do not pass the kernel 6.2.1937.
